▼ This study investigated perceptual differences in stimuli viewed with one eye (monocular) or two eyes (
binocular) in the central (fovea) and peripheral retina (10° retinal eccentricity). In particular, this study focused on changes in color perception for monochromatic stimuli (450 nm to 670 nm, in 20 nm steps) varying in size (1°, 1.7°, 2.25°, 2.7°, 3.7°). A hue-scaling procedure was utilized to ascertain hue perception. With this procedure, three
binocular normal and one strabismic amblyope assigned percentages to each of the four elemental hues (i. e., blue, yellow, red, and green) as well as saturation. Only one to two hue terms were allowed to describe a single stimulus, and the percentages had to sum to 100. Members of opponent-color pairs (red/green and yellow/blue) could not be used simultaneously to describe the same stimulus. Hue-scaling results from normal observers showed that, in general, smaller stimuli (1°, 1.7°, 2.25°) in the peripheral retina resulted in weaker hue perception than a 1° stimulus presented to the fovea, although this reduction was less noticeable for the
binocular peripheral conditions than for the monocular peripheral conditions, and more noticeable for the monocular nasal retinal condition than the monocular temporal retinal condition. Differences between peripheral and foveal hue perception abated as stimulus size increased. Additionally, the range of wavelengths where blue (yellow) was perceived was narrower (wider) in the periphery relative to the fovea for all stimulus sizes. No differences were observed between monocular and
binocular foveal hue or saturation perception, where only one stimulus size was used (1°). Peripherally-presented
binocular stimuli fell upon the nasal retina of one eye and the temporal retina of the other, and peripheral
binocular hue and saturation perceptions for smaller stimuli were more similar to that of the monocular temporal retina, regardless of whether the stimulus fell on the temporal retina of the left or right eye. Since hue-scaling data were obtained for several stimulus sizes in the peripheral retina it was possible to derive the size of perceptive fields, which are perceptual analogues of receptive fields and indicate the stimulus size at which hue perception stabilizes; i.e., the size at which amount of perceived hue ceases to increase with further increase in stimulus size. Perceptive fields measured in the monocular nasal retina were larger than those measured in the monocular temporal retina for all elemental hues. Overall, monocular perceptive fields were larger than the
binocular perceptive fields. Possible physiological reasons for the findings include suppression of chromatic signals by rod photoreceptors, differences in cone photoreceptor distribution and relative ratios of cone types over the surface of the retina, and changes in the nature of the connections of the cone photoreceptors to their associated ganglion cells with increasing retinal eccentricity. The amblyopic observer was found to have abnormal hue and…

Adult Plasticity of a Binocular Integration Mechanism.

▼ Although the visual system’s susceptibility to plasticity early in development is especially pronounced (Hubel and Wiesel, 1965, 1970), research has shown that plasticity occurs in adult visual processing as well (Gilbert, 1992; Heinen & Skavenski, 1991). Previous research (Hollins & Hudnell, 1980; Klink, Brascamp, Blake, & Van Wezel, 2010) has proposed that inducing adult plasticity is possible through visual adaptation to dichoptically incongruent spatial gratings, so that each eye sees an independent image. This type of viewing produces a perceptual phenomenon called
binocular rivalry. The visual system’s incapability of focusing on both images simultaneously subjects the viewer to constant perceptual switching, so that only one image dominates perceptual awareness at a time (Alias & Blake, 2005). Prolonged
binocular rivalry may thus impose experience-driven plasticity on the
binocular integration system. Persistent viewing of incongruent images weakens an interocular inhibition mechanism that normally suppresses the
binocular integration of opposing stimuli, and remains weakened until exposed to normal, congruent
binocular vision once more (Hollins & Hudnell, 1980; Klink et al., 2010). Perceptually, the viewer increasingly experiences mixtures of incongruent images or decreasing perceptual exclusivity. The present study extended this paradigm by randomly assigning participants to one of four interocular orientation difference (IOD) groups (90º, 45º, 37.5º, and 30º). It was expected that reducing IOD would also reduce interocular inhibition. The manipulation permits a direct test of the hypothesis that perceptual adaptation stems from weakened interocular inhibition. A significant reduction in perceptual exclusivity was found between the 30º IOD and other IOD conditions, as well as between the 37.5º and 45º IOD conditions. However, the study failed to produce decreased perceptual exclusivity with respect to time for any IOD condition, including the 90º IOD which was intended to replicate experimental conditions utilized in previous research (Hollins & Hudnell, 1980; Klink et al., 2010). The discrepancy in these findings may stem from a larger (n=60), more diverse, and inexperienced sample of observers. It is also possible that the small IOD conditions fell within a perceptual threshold that begins to elicit stereopsis (Blakemore, Fiorentini, & Maffei, 1972) in observers, despite the lack of adaptation effects.

▼ Objective: Binocular vision provides the most accurate and precise depth information; however, many people have impairments in binocular visual function. It is currently unknown whether depth information from another modality can improve depth perception during action planning and execution. Therefore, the goal of this thesis was to assess whether somatosensory input improves target localization during the performance of a precision placement task. It was hypothesized that somatosensory input regarding target location will improve task performance.
Methods: Thirty visually normal participants performed a bead-threading task with their right hand during binocular and monocular viewing. Upper limb kinematics and eye movements were recorded using the Optotrak and EyeLink 2 while participants picked up the beads and placed them on a vertical needle. In study 1, somatosensory and visual feedback provided input about needle location (i.e., participants could see their left hand holding the needle). In study 2, only somatosensory feedback was provided (i.e., view of the left hand holding the needle was blocked, and practice trials were standardized). The main outcome variables that were examined were placement time, peak acceleration, and mean position and variability of the limb along the trajectory. A repeated analysis of variance with 2 factors, Viewing Condition (binocular/left eye monocular/right eye monocular) and Modality (vision/somatosensory) was used to test the hypothesis.
Results: Results from study 1 were in accordance with our hypothesis, showing a significant interaction between viewing condition and modality for placement time (p=0.0222). Specifically, when somatosensory feedback was provided, placement time was >150 ms shorter in both monocular viewing conditions compared to the vision only condition. In contrast, somatosensory feedback did not significantly affect placement time during binocular viewing. There was no evidence to support that motor planning was improved when somatosensory input about end target location was provided. Limb trajectory showed a deviation toward needle location along azimuth at various kinematic markers during movement execution when somatosensory feedback was provided. Results from study 2 showed a main effect of modality for placement time (p=0.0288); however, the interaction between modality and vision was not significant. The results also showed that somatosensory input was associated with faster movement times and higher peak accelerations. Similar to study one, limb trajectory showed a deviation toward needle location at various kinematic markers during movement execution when somatosensory feedback was provided.
Conclusions: This study demonstrated that information from another modality can improve planning and execution of reaching movements under certain conditions. It may be that the role of somatosensory input is not as effective when practice is not administered. It is important to note that despite the improved performance when somatosensory input was…

▼ In
binocular vision, performance may be superior or inferior to monocular performance depending upon the stimuli presented to each eye. In addition, monocular or
binocular visual performance may be affected by the presence of features surrounding a target stimulus. The aim of this study was to investigate the impact of interocular stimulus similarities on a foveal acuity task in normally sighted children and adults.Liquid crystal shutter goggles synchronized with the monitor frame rate were used to present a Landolt C and surround bars to one or both eyes, in the following four viewing conditions. • Monocular: the Landolt C surrounded by bars was presented to the tested eye while the non-tested eye was occluded with a black opaque patch.•
Binocular: the Landolt C surrounded by bars was presented to both eyes.• Dichoptic: the Landolt C was presented to the tested eye and flanking bars were presented to the non-tested eye.• Half-
binocular: the Landolt C was presented to the tested eye and flanking bars were presented to both eyes. Discrimination of the orientation of a Landolt C was measured under each condition in 56 normally sighted children (7 to 14 years of age) and 22 adults (21 to 38 years of age). The effect of the surround bars (crowding) was tested in a subgroup of 9 children, and 10 adults.Across all age groups acuity was significantly better in the
binocular condition than in the other three viewing conditions (
binocular summation), and was significantly better in the half-
binocular than in the dichoptic condition. In children, but not in adults, acuity was significantly better without than with bars.Interocular similarities may explain the enhanced visual acuity in the half-
binocular condition in comparison with the dichoptic condition for all age groups tested. The results suggest that interocular interactions underpinning discrimination under these viewing conditions are developed in early childhood. The foveal crowding effect is immature at the beginning of school age, and maturation involves a reduction of this effect. These findings may have implications for the design of stimuli for
binocular vision training therapies.

▼ Adaptation to a blurred image causes a physically focused image to appear too sharp, and shifts the point of subjective focus toward the adapting blur, consistent with a renormalization of perceived focus. We examined whether and how this adaptation normalizes to differences in blur between the two eyes, which can routinely arise from differences in refractive errors. Observers adapted to images that were isotropically blurred or sharpened by varying the slope of the amplitude spectrum, or to oriented blur in images filtered to simulate different levels and axes of astigmatism. Adaptation to both types of blur produced strong aftereffects that showed strong transfer across the eyes. Greater transfer was found for the isotropic blur than for the oriented blur, both in a monocular adaptation task and in a contingent adaptation task in which the two eyes were simultaneously exposed to different blur levels. These contingent aftereffects were more robust for the astigmatic blur. When one eye was exposed to a sharper image than the other, the aftereffects instead showed little interocular difference and were strongly dominated by the sharper image. Our results suggest that while short term adaptation can rapidly recalibrate the perception of blur, it cannot do so independently for the two eyes, and that the
binocular adaptation of blur is determined largely by the sharper of the two eye's retinal images.

EVALUATION OF COMPUTERISED PROGRAMS FOR THE DIAGNOSIS AND

▼ Computerised diagnostic testing and computerised
vision training (VT) have been developed for the orthoptic
management of
binocular vision (BV) anomalies in clinical practice.
Computerised measurement of BV is assumed to assist accurate
diagnosis of BV anomalies because variability of testing resulting
from subjective judgements of examiners is eliminated by automatic
measurements. Computerised VT is thought to be effective in the
treatment of BV anomalies because the computer games used for
vision training will enhance the patient’s motivation. However,
these assumptions were lacking scientific support. This thesis
reports a range of studies to investigate the computerised programs
of diagnostic testing (HTS-BVA) and
vision training (HTS-iNet) in
comparison with corresponding traditional approaches,
respectively.The first study was to investigate inter-session
repeatability of computerised testing on BV functions. The study
results showed that computerised testing on measuring near
horizontal fusional vergence (FV) and accommodative facility (AF)
did not present higher inter-session repeatability than
corresponding traditional testing.The second study was a pilot
study for a future rigorous randomized clinical trial (RCT)
investigating effectiveness of computerised VT as a home-based
treatment for convergence insufficiency (CI). The study results
showed the subjects with CI demonstrated improvement of near point
of convergence (NPC), near base-out FV and symptoms associated with
CI after an 8-week treatment regime. The third study, following
from the first study, was to investigate whether accommodative
responses (AR) are affected by the novel accommodative stimuli used
in computerised AF testing. The study results showed the AR might
be affected by the colours of accommodative targets and the colour
filter used. Especially, the data of accommodative demand of 4
dioptres revealed that blue targets presented poorer AR than red
targets, and the targets seen with colour filters presented poorer
AR than those seen without colour filters. The fourth study, also
following from the first study, was to investigate whether a
prolonged near
vision task affects measurements made relating to
the near FV system, thus contributing to the variability of
clinical findings. The study results showed statistically
significant changes in NPC and near dissociated phoria. In further
sub-group analyses, the subjects with an initially poor NPC (n = 9)
presented greater changes in the NPC and near dissociated phoria
than the subjects with normal poor NPC (n = 25).Overall, the
computerised testing did not show more repeatable BV measurements
than the traditional testing. Finally, an RCT is needed to
determine if the computerised VT is more effective than placebo
computerised VT as a home-based treatment for CI.

▼ Computerised diagnostic testing and computerised vision training (VT) have been developed for the orthoptic management of binocular vision (BV) anomalies in clinical practice. Computerised measurement of BV is assumed to assist accurate diagnosis of BV anomalies because variability of testing resulting from subjective judgements of examiners is eliminated by automatic measurements. Computerised VT is thought to be effective in the treatment of BV anomalies because the computer games used for vision training will enhance the patient's motivation. However, these assumptions were lacking scientific support. This thesis reports a range of studies to investigate the computerised programs of diagnostic testing (HTS-BVA) and vision training (HTS-iNet) in comparison with corresponding traditional approaches, respectively. The first study was to investigate inter-session repeatability of computerised testing on BV functions. The study results showed that computerised testing on measuring near horizontal fusional vergence (FV) and accommodative facility (AF) did not present higher inter-session repeatability than corresponding traditional testing. The second study was a pilot study for a future rigorous randomized clinical trial (RCT) investigating effectiveness of computerised VT as a home-based treatment for convergence insufficiency (CI). The study results showed the subjects with CI demonstrated improvement of near point of convergence (NPC), near base-out FV and symptoms associated with CI after an 8-week treatment regime. The third study, following from the first study, was to investigate whether accommodative responses (AR) are affected by the novel accommodative stimuli used in computerised AF testing. The study results showed the AR might be affected by the colours of accommodative targets and the colour filter used. Especially, the data of accommodative demand of 4 dioptres revealed that blue targets presented poorer AR than red targets, and the targets seen with colour filters presented poorer AR than those seen without colour filters. The fourth study, also following from the first study, was to investigate whether a prolonged near vision task affects measurements made relating to the near FV system, thus contributing to the variability of clinical findings. The study results showed statistically significant changes in NPC and near dissociated phoria. In further sub-group analyses, the subjects with an initially poor NPC (n = 9) presented greater changes in the NPC and near dissociated phoria than the subjects with normal poor NPC (n = 25).Overall, the computerised testing did not show more repeatable BV measurements than the traditional testing. Finally, an RCT is needed to determine if the computerised VT is more effective than placebo computerised VT as a home-based treatment for CI.

▼ The responses of complex cells in the mammalian visual system are often modeled by the disparity energy model. The model linearly combines inputs from binocular simple cells, whose responses are computed by the combination of left and right eye inputs through linear receptive fields, followed by half squaring. However, many cells’ responses cannot be explained by this model. While it has been extended to explain some specific types of tuning, actual neurons display richer characteristics than can be fully accounted for by these models. Here, we describe a two layer simple cell model that can be used to construct complex cells that fully cover this range. The model combines the responses from a first layer of monocular simple cells. By adjusting the weights from the monocular to a second binocular layer, the model can exhibit more diverse tuning properties than previous models. We show that these weights can be learned by sparse coding, and that if so, there is a strong relationship between distribution of tuning properties in the population and the input disparity statistics. Our simulation results also show that the modeled population evolves towards the data recorded from cat Area 18, and we can find the optimal input disparity distribution resulting in the most similar population with the recorded data. By changing the wavelength of model receptive field, we demonstrate that the standard deviation of the optimal input disparity distribution increases with the wavelength.

▼ Joint development of perception and behavior based on efficient coding theory has been proposed and proved to be an effective approach in the study of eye movements. Disparity vergence, one type of eye movement, is believed to achieve robustness and accuracy by the cooperation between fovea and periphery. Complicated realistic environments, where objects in different depths project conflicting disparity information on different regions of the retina, cannot be handled well by previous joint development models of vergence control, which combine information from fovea and periphery in parallel. Here, we propose a hierarchical approach to integrating foveal and peripheral vision for vergence control. The model consists of two levels. At the bottom level, three options receive input from the fovea, the inner periphery, the outer periphery of the retina. At the top level, a policy chooses one of the three options for vergence control. Our experimental results show that the hierarchical model for integration of fovea and periphery provides more accurate and robust vergence control than a previous model where the sensory representation from different scales was combined in parallel. In addition, the hierarchical model shows good performance in dealing with a wide range of situations, such as small objects moving in depth, a lack of content in the fovea, and occlusion. Furthermore, a periphery to fovea process is observed when applying the hierarchical model in vergence control, which is consistent with psychological evidence found by other researchers.

▼ Summary: In the present study, it was examined whether the spatiotemporal dynamics of
transitions towards target dominance in motion-induced blindness (MIB) were wave-like,
similar to those in binocular rivalry. The spatiotemporal dynamics of transitions towards
dominance in MIB were further compared with those in binocular rivalry to reveal a
potential neural locus of MIB. Across a series of experiments, the relationship between
target length, stimulus structure, presentation location and the latency for circular arc
segment-shaped targets to reappear was examined, respectively. It was found that target
reappearance durations increase with target length, as if they reappear in a gradual, wavelike
fashion. Target reappearance durations were decreased for collinear compared to
radial targets, but they were not influenced by the location of target presentation. The
results suggest MIB target reappearances are associated with traveling waves of
dominance, and early visual cortex is a likely neural substrate in which these wave-like
transitions occur.

▼ There are several sources of visual information about motion. One is simply the motion on the retina, known as optic flow, caused by motion in the world. Another source of flow-based information is the differences between the optic flow fields of the two eyes, known as interocular velocity differences. Also, there is disparity-based information about motion in the form of the changes in
binocular disparity over time that result from motion. This dissertation concerns the results of experimental work to determine the functional differences between the systems that utilize these sources of information. In the context of perception of time-to-contact, flow-based information is used to perceive objects moving at high velocity and disparity-based information is used to perceive objects moving at low velocity. When both are available, these cues are not combined. Instead, humans just rely on the superior form of information, given the object’s velocity. In the context of perception of lateral motion, there are greater latencies when processing disparity-based information than when processing flow-based information. Despite this, disparity-based information alone is sufficient to guide perception of, and coordination with, laterally moving objects with no decrease in performance compared to normal viewing conditions that present all sources of motion
information. I also discuss work that showed how important motion information is to the perception of static properties like object shape. Specifically, ths work demonstrated that both flow- and disparity-based information are necessary for perception of metric shape, as is 45° or more of continuous perspective change. In addition, static disparity alone is not enough; dynamic changes in disparity are required. Our data suppor1 the way in which the model of R. Foster et al. (2011) combines this information, although this model needs to be revised because it assumed combination of flow and static disparity, not dynamic changes in disparity. Over the course of this work, I have revisited several well-researched perceptual and perceptuomotor tasks and investigated the roles of flow-and disparity-based motion information in their execution. This work has shed light on both the mechanisms that underlie motion perception and the role of motion perception in other tasks.

▼ The aim of this study was to add to our understanding of interocular interactions in normally sighted children (Group I, N=20), normal adults (Group II, N=20) and adults with anisometropic amblyopia (N=12) by investigating responses to a range of visual functions under three kinds of viewing condition. Visual functions tested were visual acuity, contrast sensitivity and alignment sensitivity.Stimuli were generated on a Cambridge VSG card driving a high resolution monitor and FE liquid crystal goggles, enabling three kinds of viewing conditions:1. Monocular (non-tested eye occluded), used as a baseline for most functions.2. Dichoptic (uniform field presented to the non-tested eye but with a binocular fusion lock).3. Binocular.In general, binocular performance was better than monocular (binocular summation) but so too was dichoptic performance (dichoptic advantage). However there was much variation within individuals (the three functions showing different summation/advantage pattern) and between individuals.Significant conclusions include:(a) Maturational windows for interocular interactions differ for different spatial visual functions.(b) Interpretations of results from one visual function cannot be applied automatically to other functions.(c) Care must be taken in interpreting results based on 5 or fewer subjects.

▼ Making inferences about the 3-dimensional spatial structure of natural scenes is a critical visual function. While spatial discrimination both in depth and on the image plane has been well characterized for simple stimuli, little is known about our ability to discriminate depth in natural scenes, particularly at far distances. To begin filling in this gap we: (i) developed a database of 80 stereoscopic images paired with the corresponding measured distance information, (ii) used these scenes as psychophysical stimuli and measured near-far discrimination acuity in 4 observers as a function of distance and the visual angle separating the targets, (iii) made additional measurements under patched-eye (monocular) viewing conditions to evaluate the importance of
binocular vision in depth discrimination as a function of viewing geometries. We find that
binocular thresholds are roughly a constant Weber fraction of the distance for absolute distances ranging from 4 to 28 meters. Further, measured thresholds were around 1% for small separations, and increased to 4% for stimuli separated by 10 deg. Thus, the ability to discriminate depth in natural scenes is very good out to considerable distances. To investigate the basis of this discrimination ability, monocular thresholds were measured. We found that monocular thresholds were elevated for distances less than 15 meters, but were comparable to
binocular thresholds for greater distances. Accurate depth perception depends on combining (fusing) multiple sources of sensory information. Thus
binocular thresholds probably involve fusing separate monocular and disparity-derived estimates. Under the assumption of Gaussian distributed independent estimates, Bayes rule provides a simple reliability-weighted summation model of cue combination. Using disparity threshold measurements by Blakemore (1970), and the current monocular thresholds, parameter-free predictions were generated for the current
binocular thresholds. These predictions were in broad agreement with the data, suggesting that the disparity and monocular cues are separable and combined optimally in natural scenes.

▼ In mammals, binocular fusion takes place over a limited region, known as Panum's fusional area, which is much smaller than the range of binocular disparities encountered in natural scenes. This discrepancy suggests that there must be a mechanism for detecting whether the stimulus disparity is inside or outside the range of the preferred disparities of disparity-tuned neurons in the brain. However, this mechanism has received little attention to date. This thesis describes a biologically-plausible approach to address this detection problem. We compare the efficacy of several features computed from a population of disparity-tuned neurons as confidence measures that differentiate between in-range and out-of-range disparities. Interestingly, some intuitively appealing features, such as the average activation across the population and the difference between the peak and average responses, actually perform poorly. On the other hand, we find that normalizing the difference between the peak and average responses results in a reliable confidence measure. We validate our findings experimentally using both real and synthetic images, and theoretically using a probabilistic model of the population responses. This probabilistic model also enables us to derive a biologically-plausible detector which combines multiple features to improve the performance. Using this normalized feature, we also propose a new approach to estimate the stimulus disparity. The model computes the confidence for neural populations and estimates the disparity from the population with the highest confidence. In contrast to the sequential approach in a previously proposed coarse-to-fine model, our model operates in parallel. Working on real-world stereograms, our approach outperforms the coarse-to-fine model and it has the ability to identify occluded regions. Finally, we demonstrate the efficacy of the confidence measure in a stereo vision system. The system can compute and evaluate the population responses of disparity-tuned neurons in real time, and it can control virtual vergence eye movements.

▼ Accommodative insufficiency is a
binocular vision
disorder characterized by a decrease in age expected amplitudes of
accommodation. This condition can result in symptoms of headaches,
blurred
vision and asthenopia.
Vision therapy has been utilized in
helping treat patients with accommodative insufficiency. The
purpose of this study was to evaluate the repeatability of the
Convergence Insufficiency Symptom Survey (CISS) in subjects with
accommodative insufficiency. This study also examined the
improvement in CISS scores following 8 weeks of weekly 1-hour
office-based
vision therapy with home reinforcement. Improvements
in accommodation and vergence measures were also examined as part
of this study. Subjects ages 9 to 30 were enrolled in the study.
Measures of amplitudes of accommodation, accommodative facility,
accommodative response, and vergence function were evaluated at
baseline and were repeated following 8 weeks of
vision therapy.
Final outcome sensorimotor measures and CISS scores were collected
by examiners masked to the subject’s progress and compliance with
vision therapy. Using the method described by Bland-Altman, the
CISS was found to be repeatable in subjects with accommodative
insufficiency. The mean difference in scores between two
administrations was 1.47 point with 95% limits of agreement of
-5.19 and 8.13. Analysis using student’s t or the Wilcoxan sign
rank test showed a statistically significant improvement in
amplitudes of accommodation (AA) (p<0.001), monocular
accommodative facility (MAF) (p≤.0009) and amplitude scaled
monocular accommodative facility (MAF-S) (p≤.034). Statistically
significant improvements in CISS scores were also noted (p=0.0003).
Accommodative function is known to decrease with increasing age.
Therefore, differences in improvements between adults and children
were also investigated. The Kruskal-Wallis test showed
statistically significant differences in improvements between age
groups in AA, MAF, and CISS. The results of this study show that 8
weeks of weekly 1-hour office-based
vision therapy and home
reinforcement results in a decrease of symptoms and increase in
accommodative measures in patients with accommodative
insufficiency.

▼ PURPOSE: To prospectively evaluate the
effectiveness of home-based computer vergence therapy for treatment
of
binocular vision disorders in adults, ages 18-85, at least 3
months post brain injury. METHODS: Eligibility
criteria included presence of
binocular or accommodative
dysfunction characterized by receded near point of convergence
(NPC) (greater than or equal to 6 cm break), insufficient positive
fusional vergence (PFV) at near (failing Sheard’s criterion or less
than 15Δ blur or break), insufficient negative fusional vergence
(NFV) at near (less than 12Δ blur or break), reduced vergence
facility with 12ΔBO/3ΔBI at near (less than 15 cpm), and/or below
minimum expected amplitude of accommodation for age. All subjects
were prescribed 12 weeks of home-based computer vergence therapy.
Phoria (cover test), NFV at near, PFV at near, NPC, vergence
facility, accommodative amplitude and facility (nonpresbyopes
only), and symptoms (convergence insufficiency symptom survey
[CISS]) were assessed at baseline and after 4, 8 and 12 weeks of
prescribed therapy. ANOVA was used to evaluate change in each
measure. Percent successful also was determined.
RESULTS: Of the 19 subjects enrolled (mean age
45.4 ± 12.9 years), 15 suffered external mechanical trauma to the
head, 3 suffered cerebrovascular accident, and 1 suffered from
organic brain syndrome. Six subjects were lost to follow-up. The
binocular profile of the cohort at baseline was orthophoria
(SD=1.08) at distance, 7.11Δ (SD=5.19) exophoria at near, NPC break
= 17.07 cm (SD=10.56), NPC recovery = 21.48 cm (SD=11.66), near NFV
= 12.33Δ (SD=4.37), near PFV = 8.80Δ (SD=5.69), vergence facility =
4.06 cpm (SD=4.41), and CISS = 31.12 (SD=12.93). ANOVA showed
statistically significant improvement for NPC break (p=0.002) and
recovery (p less than .001), PFV blur (p less than .0001), break (p
less than .0001), and recovery (p less than .0001), NFV blur
(p=0.047), break (p=0.008), and recovery (p=0.017), vergence
facility (p less than .0001), and CISS (p less than .0001). The
percentage of patients who were classified as “successful” or
“improved” was 69% for NPC (less than 6 cm or a decrease of greater
than 4 cm), 77% for PFV (greater than 15Δ and passing Sheard’s
criterion or an increase of greater than or equal to 10Δ), 77% for
NFV (greater than or equal to 12Δ or an increase of greater than or
equal to 6Δ), 69% for PFV and NFV, 92% for vergence facility (15
cpm or an increase of 3 cpm), and 62% for CISS (less than 21 or a
decrease of greater than or equal to 10
points). CONCLUSIONS: The majority of the 68% of
subjects who completed the study experienced meaningful
improvements in signs and symptoms.

▼ The perceived relative direction of a pair of features can be intermediate between their relative direction in the two eyes. It is known that the perceived relative direction of the features can be altered by making their disparity gradient steep. Features at the edge between two surfaces at different depths form steep disparity gradients. These features are typically next to features on the same surface with the same disparity. These additional features were found to mitigate the effect of steep disparity gradients on perceived direction. The effect of the additional features was found to vary with their contrast, their contrast polarity and their separation relative to the features that define a steep disparity gradient. Hence, these stimulus properties determine whether disparity gradients affect the perceived direction of features at surface edges. That the perceived relative direction of a pair of features can be an average of the angles that they subtend at each eye supports the theory that perceived visual directions are referred to a point midway between the eyes (cyclopean eye). However, from this reference point, an occluding surface would hide features on the background that are visible to the left eye next to its left edge or visible to the right eye next to its right edge. Ono et. al. (2002) proposed that the perceived direction of these features is shifted laterally from their true direction when the occluder is fixated and the occluder is shifted in the opposite direction when the background is fixated. Erkelens et. al. (1996) proposed that the perceived direction of features is referred to the eye that views the monocular region instead of a cyclopean eye so that both surfaces may be perceived in their true direction. In the present study, two occluders were arranged so that a left side edge was physically aligned with a right side edge. The monocularly visible background texture next to these edges was also physically aligned. Consistent with the first proposal, the monocular regions or the edges of the occluders were found to appear laterally offset from one another indicating that their perceived direction was incorrect. Erkelens et. al. (1996) found that the perceived direction of the left and right edges of an occluding surface relative to a line on the background was found to be more strongly influenced by their position in the eye that views the monocular region of the background next to the edge than by their position in the other eye. In the present study, this Erkelens-bias was found with fixation on the background surface, but was not found with fixation on the occluder, which is also consistent with the first proposal. The Erkelens-bias decreased with the lateral separation of a target line on the occluder from its edge. The Erkelens-bias was found even when all texture on the surfaces was eliminated except for the outline of a foreground surface and a single line on the background surface. This indicates that the Erkelens-bias does not require the presence of either steep disparity…

▼ The human, along with other primates, has forward placed eyes, and an area of acute vision (the fovea) on each retina. The overlap of the visual fields and the hemi-decussation of the visual pathways at the optic chiasm provide the basis for binocular vision, in particular stereopsis, the accurate perception of the position of objects in three dimensional space and an improved ability to perceive the form of solid objects. An intricate system of eye movements is needed to achieve and maintain stable foveal fixation on each eye in an environment where visual targets vary in direction and depth, where the visual environment may be moving, the eyes or the rest of the body is moving. The purpose of this study is to evaluate the accuracy of binocular alignment for far and near fixations, under relatively natural conditions. To achieve binocular fixation, accurate vergence eye movements are required to align the eyes, and to maintain this alignment when a person changes fixation to objects situated at different distances from the eyes. ‘Pure’ vergence eye movements occur when these objects are situated along the mid sagittal plane, however, in natural conditions other eye movement systems are also involved. To understand the contribution of different eye movement systems to binocular fixation at different distances, the accuracy of binocular alignment in subjects with normal binocular single vision was evaluated in subjects with normal binocular vision under the following conditions • Fixation on targets along the mid sagittal plane (vergence eye movements only) • Fixation on targets displaced to either side of the mid sagittal plane (combined vergence eye movements and saccades • Fixation on earth fixed targets situated straight ahead in space, but with the head tilted to either side (combined vergence eye movements, saccades and torsional eye movements). The protocol for all experiments was approved by the Human Ethics Committee of the University of Sydney and followed the tenets of the Declaration of Helsinki. Throughout this thesis the term ‘binocular alignment’ will be used to describe the position of each eye during or following a change in vergence. The term ‘vergence error’ will refer to situations where the angle of vergence alignment is different from that required, so that the image of the fixation target does not fall on the fovea of one or both eyes.

▼ Humans move through the environment without loosing balance or bumping into other objects or organisms. In order to achieve this ability, the brain uses incoming information from several senses. If stationary observers receive information from the visual system signaling self-motion through the environment, while information from the vestibular and proprioceptive systems suggest a stationary observer, visual information overrides the information from both other sensory systems. As a consequence, observers start to sway. The main focus of this thesis was on whether only direct visual stimulation (i.e. visual motion presented to the retina; a stimulus-response mechanism) or also indirect visual stimulation (i.e. motion not presented to retina but generated internally) induces postural sway. Specific stimulus characteristics were manipulated and illusory visual motion signals in the absence of external visual stimulation were used to investigate this question.
As a first question, we have investigated whether the strength of perceived self-motion and the induced postural sway magnitude are directly related. Radial optic flow patterns simulating self-motion through the environment were presented to stationary observers. Rigid optic flow patterns generated a stronger sensation of self-motion but generated less postural sway than non-rigid optic flow patterns. Apparently, visuo-vestibular interactions are tailored to compensate for rigid optic flow stimuli. Additionally, we showed that an often-observed directional anisotropy in postural sway between expanding and contracting optic flow did not have a biomechanical origin. To avoid this directional anisotropy, we used horizontal translating dot patterns to examine whether the perceptual strength (manipulated by varying the speed and dot contrast) of a stimulus influences the postural sway magnitude. Results showed that the induced sway magnitude and sway direction depend on the speed and contrast of a stimulus moving in a single direction. This result suggests that visuo-vestibular interactions are influenced by an internal representation of visual motion, rather than being a direct consequence of the stimulus. Further evidence for such an internal representation of visual motion influencing postural sway, was provided by the finding that the illusory motion generated by the motion aftereffect induced postural sway as well.
We also examined two perceptual predictions derived from the sway results. First, we expected an asymmetry in perceptual strength between radial optic flow directions to mirror the directional anisotropy apparent in postural sway. However, the results showed the opposite asymmetry, suggesting an inverse relationship between the perceptual strength of radial optic flow directions and the induced postural sway magnitude. This perceptual asymmetry was also observed at the level of perceptual grouping during
binocular rivalry. Grouped expanding optic flow was perceived for longer durations than grouped contracting optic flow, but only when the structure…

▼ An important aspect of human
vision is the fact that it is
binocular, i.e. that we have two eyes. As a result, the brain nearly always receives two slightly different images of the same visual scene. Yet, we only perceive a single image and thus our brain has to actively combine the
binocular visual input into a single, cyclopean view of the world. Using both behavioral and neuroimaging approaches we studied where in the brain this process of
binocular integration might take place and what can happen if the integration of information from the two eyes fails. Using computational neuroimaging techniques we demonstrate that the first cortical area that is involved in processing visual information (primary visual cortex, V1) represents a visual scene as it appears on the retina: with two slightly differing images. Starting from the second visual cortical area (V2) the representation of visual scenes is mostly integrated into the single, cyclopean view that we experience in daily life. We also found that when the integration of
binocular information does not function properly people can develop a particular deficit that we termed motion agnosia. This deficit results in the observer being unable to discriminate between different directions of motion, essentially making them unable to correctly judge which way objects are moving. However, this deficit occurs without any other abnormality in the eyes or
vision in general and therefore we concluded that it is best described as a form of visual agnosia: a disorder where the visual information is still available (the eyes function normally) but the observer is unable to use that information to make inferences about the environment. Using behavioral methods (psychophysics) and fMRI we demonstrate that the origin of motion agnosia is the
binocular combination of motion signals from the two eyes.

▼ Stereo vision is one of the representative technologies in the 3D camera, using multiple cameras to perceive the depth information in the three-dimensional space.
The binocular one has become the most widely applied method in stereo vision.
So in our thesis, we design a binocular stereo vision system based on an adjustable narrow-baseline stereo camera, which can simultaneously capture the left and right images belonging to a stereo image pair.
The camera calibration and rectification techniques are firstly performed to get rectified stereo pairs, serving as the input to the subsequent step, that is, searching the corresponding points between the left and right images.
The stereo matching algorithm resolves the correspondence problem and plays a crucial part in our system, which produces disparity maps targeted at predicting the depths with the help of the triangulation principle.
We focus on the first stage of this algorithm, proposing a CNN-based approach to calculating the matching cost by measuring the similarity level between two image patches.
Two kinds of network architectures are presented and both of them are based on the siamese network.
The fast network employs the cosine metric to compute the similarity level at a satisfactory accuracy and processing speed.
While the slow network is aimed at learning a new metric, making the disparity prediction slightly more precise but at the cost of spending way more image handling time and counting on more parameters.
The output of either network is regarded as the initial matching cost, followed by a series of post-processing methods, including cross-based cost aggregation as well as semi-global cost aggregation.
With the trick of Winner-Take-All (WTA), the raw disparity map is attained and it will undergo further refinement procedures containing interpolation and image filtering.
The above networks are trained and validated on three standard stereo datasets: Middlebury, KITTI 2012, and KITTI 2015.
The contrast tests of CNN-based methods and census transformation have demonstrated that the former approach outperforms the later one on the mentioned datasets.
The algorithm based on the fast network is adopted in our devised system.
To evaluate the performance of a binocular stereo vision system, two types of error criteria are come up with, acquiring the proper range of working distance under diverse baseline lengths.

▼ The Pedestrian Detection System (PDS) has become a significant area of research designed to protect pedestrians. Despite the huge number of research work, the most current PDSs are designed to detect pedestrians without knowing their distances from cars. In fact, a priori knowledge of the distance between a car and pedestrian allows this system to make the appropriate decision in order to avoid collisions. Typical methods of distance measurement require additional equipment (e.g., Radars) which, unfortunately, cannot identify objects. Moreover, traditional stereo-vision methods have poor precision in long-range conditions. In this thesis, we use the keypoint-based feature extraction method to generate the parallax in a binocular vision system in order to measure a detectable object; this is used instead of a disparity map. Our method enhances the tolerance to instability of a moving
vehicle; and, it also enables binocular measurement systems to be equipped with a zoom lens and to have greater distance between cameras. In addition, we designed a crossover re-detection and tracking method in order to reinforce the robustness of the system (one camera helps the other reduce detection errors). Our system is able to measure the distance between cars and pedestrians; and, it can also be used efficiently to measure the distance between cars and other objects such as Traffic signs or animals. Through a real word experiment, the system shows a 7.5% margin of error in outdoor and long-range conditions.

▼ A model of stereopsis is proposed in which information from each eye's image is organised as a scale-based hierarchy before binocular comparison. The algorithm incorporates coarse-to-fine matching (like Marr and Poggio, 1979) but differs from previous models in that the position, and hence disparity, of features is defined relatively rather than by their retinal co-ordinate. Thus, fine scale disparities are measured and recorded relative to coarse scale disparities. Local surface slant and curvature is represented explicitly at a range of spatial scales. The theory is based on a hierarchical model of encoding position (Watt, 1988). The first experiment investigates the time course of shape discrimination in random dot stereograms. The results are compatible with a model in which the scale of analysis changes from coarse to fine over the first second of viewing. The second experiment measures the magnitude of a new "3-D" Müller-Lyer illusion and compares it to that of the classical (2-D) illusion. Both these and the cyclopean Müller-Lyer illusion are consistent with a model in which hierarchical encoding of position is used by the visual system for 2-D (length comparison) and 3-D (slant) judgements. The third experiment compares the detection of large disparities and large displacements. "Dmax" for the motion and stereo tasks is shown to be similar over a wide range of dot densities. The results are interpreted as evidence that similar spatial primitives are used in the correspondence process in both domains. The spacing of MIRAGE centroids (Watt and Morgan, 1985) fit the data well. The proposed hierarchical model is similar to that put forward by Mitchison and McKee (1987), although their scheme was not based on spatial scale. The model bridges the gap between a primal and a 2 1/2-D sketch (Marr, 1982) and has important implications for many issues within stereopsis.

▼ When viewing a real object, our eyes will accommodate to focus at the object. At the same time, our eyes will also verge so that the visual axis of both eyes will point towards that object. In other words, the vergence of eyes will change in accordance to the accommodation of the eyes. However this relationship may be disturbed when viewing stereo images with changing stereo depths presented on a binocular display with fixed lens focus. The incompatibility between the varying stereo depth and the fixed lens focus can post an unnatural demand on human vergence eye movements. This may cause eye fatigue. An experiment has been conducted to investigate the levels of eye fatigue caused by viewing stereo images with changing stereo depths on a binocular display with compatible and incompatible lens focuses. Four viewing conditions have been studied and they exhaust the factorial combinations of two lens focus (40cm and 200cm) and two changing stereo depth cues (40cm ± 0.3 dioptres and 200cm ± 0.3 dioptres). This design examines the effects of lens focus, stero depth, and their interactions (i.e., compatibility between lens focus and stereo depth). In this study, we are interested in the compatibility effects when the lens focus or stereo depth is controlled at 40cm and 200cm, respectively. When using a binocular display with fixed lens focus of 200cm, viewing stereo images with incompatible stereo depths (40cm) can significantly increase the rated levels of eye fatigue (p<0.001, F1,383 = 33, ANOVA). This is an important finding and carries serious implications to those manufacturers of binocular displays with fixed lens focus of 200cm (e.g., iMD Ltd.). Unfortunately, adjusting the lens focus of the displays to 40cm to match the stereo depths of the images did not result in significant reduction in eye fatigue (p>0.5, F1,383 = 0.36, ANOVA). The lack of benefits is due to an opposite confounding effects of accommodation on eye fatigue: as the lens focus is reduced to match with the stereo depth, the accommodative demand on the eyes is increased. The former reduces the levels of eye fatigue while the latter does the opposite. Data also indicate that when the confounding effect of accommodation is in agreement with the compatibility effects between lens focus and stereo depth, very significant reduction in rated levels of eye fatigue are reported when lens focus is changed from 40cm to 200cm in order to match with images of stereo depths of 200cm ((p<0.001, F1,383 = 55.5, ANOVA). Further discussion and implications to the design of binocular displays can be found in the thesis.

▼ Past studies in English and German texts have shown that a vertical striped word (one which consists of repetitive vertical stripe components) is associated with a longer reading and binocular fixation times. A biologically inspired reason related to binocular fixation has been proposed, which predicts that the prolonged reading time is caused by the additional effort from the binocular vision system to align an image with a high occurrence of vertical stripes projected on the left and right retinas. This study aims to investigate if the proposed theory is true in reading Chinese. In the first experiment, we planned to study whether similar effect persists in Chinese texts. Unlike English and German texts, Chinese text are not alphabetical but are logographic. Three thousand common Chinese characters (taken from a Hong Kong Baptist University Language Center report) were analyzed into three groups: (i) character with more repetitive vertical stripes; (ii) character with less repetitive vertical stripes; and (iii) neutral, using horizontal autocorrelation as an objective measurement. Three measures were utilized in the categorization process based on horizontal autocorrelation; (i) the value of first peak of the horizontal autocorrelation; (ii) difference in value of first peak and the value of the preceding trough in horizontal autocorrelation; (iii) number of peaks of horizontal autocorrelation. The results from experiment 1 and 2 have shown that a character with more repetitive vertical stripes exhibits a significantly longer recognition time than a character with less repetitive vertical stripes. This suggests that the effect of vertical stripes is not restricted on alphabetical texts. In the third experiment gaze movement were recorded throughout to identify the binocular fixation duration for each character. Results suggests that the more repetitive the vertical stripe pattern was, the longer the binocular fixation durations. In summary, the presence of vertical stripes prolonged recognition time and binocular fixation duration of Chinese characters. According to the proposed theory, in a monocular viewing condition the recognition time and fixation duration shall not be affected by the presence of vertical stripes. In addition, the presence of vertical stripes should affect the recognition of a character regardless of the reading orientation. To put the proposed theory under the test, the fourth experiment studied 3 viewing conditions; (i) horizontal binocular viewing; (ii) vertical binocular viewing; (iii) horizontal monocular viewing (non-dominant eye to be occluded). As predicted by the theory, recognition time for character with more repetitive vertical stripes is significantly longer in condition (i) and (ii), but not in condition (iii). Binocular fixation duration (while in condition (iii) it would be monocular fixation duration), is significantly longer with character with more repetitive vertical stripes in condition (i) and (ii) but not in condition (iii). The fifth experiment utilized an iCub…
