▼ The provision of environmental support is known to have differential effects on
recognition memory in younger and older adults. Age-related differences within
recognition memory were explored by investigating recollection and familiarity, and looking at their relationship with associative
recognition memory. Additionally, environmental support, manipulated by different encoding conditions, was investigated by looking at its effect on this relationship, by comparing
recognition memory for items and their associations, in younger and older adults. These were assessed by measures of subjective conscious recollection, that utilized the “remember-know” paradigm, and an objective recollection test, in which
recognition memory for associative details was assessed.
The results showed that older adults displayed no impairments in
recognition memory, however a deficit in their associative
recognition memory was discovered. Environmental support, implemented by directing attention during encoding, enhanced memory for associative details, however no effects were found on
recognition memory. The relationship between
recognition memory and associative
recognition memory was strengthened by provision of environmental support, with younger and older adults affected to a similar degree.

Fusion of face and gait for human recognition.

▼ A system that integrates the face, a physical biometric, with gait, a behavioral biometric, for automatically recognizing human beings effectively under a wider range of conditions than a classifier which exclusively employs only one of these biometrics, is proposed. A decision-level fusion approach is adopted where the top matches of the face classifier are passed on to the gait classifier which then determines the identity of the unknown person. For face
recognition, a principle components analysis-based approach, as well as a Bayesian inference-based classifier is employed, while for gait
recognition, a model-based strategy is implemented, which utilizes various gait features identified as being the most pertinent for
recognition based on data collected using an optoelectronic motion capture system. The integrated system is found to outperform the individual face and gait classifiers that it is composed of, thus, demonstrating the potential of using the gait to supplement the face in scenarios where the face classifier alone does not perform well due to the non-availability of high resolution face data. During the course of this research, automated face
recognition was also studied in detail, with a concentration on approaches that employ statistical dimensionality reduction techniques for this task. Experiments were conducted on some of the most widely-used methods in this category to test the
recognition accuracy of these methods, and various combinations thereof, for different database sizes, images resolutions and number of bits per pixel. It was found that certain combinations of some of these techniques perform better than the individual methods that those combinations are comprised of when higher resolution face images are utilized. Furthermore, a system which utilizes different resolution versions of the whole face, as well as of various facial components, in a hierarchical manner was implemented and was found to achieve higher accuracy than its single-level counterpart which uses only the highest resolution images.

▼ Human adults recognize faces extremely well; however, the way in which this expertise develops remains unknown. One developmental model of face
recognition is perceptual narrowing, which contends that at birth perception is broadly tuned, but narrows as a function of experience. According to this model, infants transition from being face generalists—broadly discriminating facial identity for numerous species—to being face specialists, who are experts in discriminating human faces. To test this model, facial identity discrimination was measured in 4- to 6-month-olds, 9- to 12-month-olds, and adults in two experiments: one using natural faces, and one using systematically varied faces. The first study revealed that 4- to 6-month-olds (n = 26) and adults (n = 27) discriminate sheep (Ovis aries) faces (ps < .05), while 9- to 11-month-olds (n = 26) showed no evidence of discrimination (p > .05). The fact that young infants discriminate sheep faces is consistent with the perceptual narrowing model, which posits that perception is broad early in the first year of life and narrows with age. However, the ability to discriminate some types of animal faces does not disappear, as we found adults could also discriminate sheep faces. In the second study, we examined the properties of faces viewers can use for discrimination by systematically varying faces of humans, capuchin monkeys (Cebus apella), and sheep (Ovis aries) in their outer features (contour, hair), inner features (eyes and mouths), or spacing among inner features (distance between eyes, vertical position of eyes and mouth). Results indicated that 4- to 6-month-olds (n = 61) showed no evidence of discriminating systematically varied faces. In contrast, 9- to 12-month-olds (n = 41) discriminated human and monkey faces that varied in either outer features or inner features (ps < .05). Adults (n = 71) discriminated all three species using inner and outer features, and additionally discriminated human and monkey faces that varied in their spacing (ps < .05). This finding suggests that adults may use configural processing for primate, but not nonprimate faces. Taken together, findings from both experiments differ from predictions derived from a perceptual narrowing model of development. An alternative model—learned attention—is discussed.

▼ Face
recognition is a specialized case of object
recognition, and has broad applications in security, surveillance, identity management, law enforcement, human-computer interaction, and automatic photo and video indexing. Because human faces occupy a narrow portion of the total image space, specialized methods are required to identify faces based on subtle differences. One such method is the Eigenfaces classifier, a holistic statistical method which significantly reduces the dimensionality of the search space.
Despite the dimensionality reduction, the k-nearest neighbor (kNN) search remains a bottleneck in this application as well as most others that use it. The kNN search is both computationally complex and highly data-parallel, making it a candidate for acceleration on graphics hardware.
I present an implementation of an Eigenfaces classifier with a portion of the kNN search accelerated on an Nvidia Tesla K20X GPU with 2688 cores.

▼ Humans are experts at recognising patterns in past experience and applying them to new tasks.
For example, after seeing pictures of a face we can usually tell if another image contains the
same person or not. Machine learning is a research discipline at the intersection of computer
science, statistics and mathematics that investigates how pattern
recognition can be performed
by machines and for large amounts of data. Since a few years machine learning has come
into the focus of quantum computing in which information processing based on the laws of
quantum theory is explored. Although large scale quantum computers are still in the first stages
of development, their theoretical description is well-understood and can be used to formulate
`quantum software' or `quantum algorithms' for pattern
recognition. Researchers can therefore
analyse the impact quantum computers may have on intelligent data mining. This approach is
part of the emerging research discipline of quantum machine learning that harvests synergies
between quantum computing and machine learning.
The research objective of this thesis is to understand how we can solve a slightly more specific
problem called supervised pattern
recognition based on the language that has been developed
for universal quantum computers. The contribution it makes is twofold: First, it presents a
methodology that understands quantum machine learning as the combination of data encoding into
quantum systems and quantum optimisation. Second, it proposes several quantum algorithms for
supervised pattern
recognition. These include algorithms for convex and non-convex optimisation,
implementations of distance-based methods through quantum interference, and the preparation of
quantum states from which solutions can be derived via sampling. Amongst the machine learning
methods considered are least-squares linear regression, gradient descent and Newton's method,
k-nearest neighbour, neural networks as well as ensemble methods. Together with the growing
body of literature, this thesis demonstrates that quantum computing offers a number of interesting
tools for machine learning applications, and has the potential to create new models of how to learn
from data.

▼ Modernization and its accompanying processes have
never lost their momentum to transform our socio-political and
economic landscape. Since the second half of the 20th century, the
studies on the influences of globalization and late capitalism have
been the major areas of studies in humanities and social science.
With increasingly inevitable exchanges between our cohabitants, the
ways to achieve non-confining and equal coexistence gain their
exigency. Hence, this dissertation would look into the concept of
mutual recognition and discuss the ways our coexistence can be
enhanced.
This dissertation first reviews the previous accounts
for our mode of existence. Among the various theories, it advocates
the concept of mutual recognition and illustrates the ways the
related theories proposed by Axel Honneth and Charles Taylor can
explicit and enhance our existence.
Apart from the positive
appraisal of their models, it exemplifies the way mutual
recognition is interdicted in their arguments by assuming an
authoritarian yet unarticulated identity. To revitalize this useful
concept, it discusses the way narrative can help articulate our
selfhood and serves as an arc for communication as in Never Let Me
Go. In brief, Charles Taylor’s discussion on emotions provides the
foundation for our active organization of selfhood and Paul
Ricoeur’s analysis on the relationship between fiction and reality
helps connect the world of fiction to the world of action. Hence,
genuine selfhood and respect for others can be achievable in their
models.
Finally, among the various narrative practices, it
explores the artistic merits of the novel studied, as an exemplary
model for this kind of writing to defense us against the hegemonic
definition and corrosion for free and equal
coexistence.

▼ The technology of human face recognition is now mature enough to be widely used in security by law enforcement agencies for dealing with criminal activities, government agencies for border control as well as government organizations and private enterprises for access control. However, there are still a lot of room for improvement.
In this thesis, we study strategies to improve the recognition accuracy. Two proposed schemes, Principal Component Analysis (PCA) and Gabor wavelet, for human face recognition are discussed and the implementations of sub-modules in each scheme are introduced.
In principal component analysis based human face recognition, we started from the basic method by first identified and developed the major testing criteria. Once the major testing criteria were developed, we analyzed those criteria which had significant impacts on the accuracy of recognition. More face databases were used in order to positively identify those criteria. Distorted images with poor illumination at the background had been identified as one of the major impacts on the accuracy of recognition. We then further investigated on this criteria and found ways to improve the results of recognition.
In Gabor wavelet based human face recognition, we first examined the classification capability of 40 different basic Gabor phase representations. We utilized those Gabor features from facial images, tested on the selected distorted images and compared the results and findings with the principle component analysis based human face recognition.

▼ Although previous research in event-related potentials (ERPs) has focused on the conditions under which faces are recognized, less research has focused on the process by which face representations are acquired and maintained. In Experiment I, participants were required to monitor for a target "Joe" face that was shown amongst a series of distractor "Other" faces. At the half-way point, participants were instructed to switch targets from the Joe face to a previous distractor face that is now labeled "Bob". The ERP analysis focused on the posterior N250 component known to index face familiarity and the P300 component associated with context
updating and response decision. Results showed that the N250 increased in negativity to target Joe face compared to the Bob face and a designated Other face. In the second half of the experiment, a more negative N250 was produced to the now target Bob face compared to the Other face. Critical1y, the more negative N250 to the Joe face was maintained even though Joe was no longer the target. The P300 component followed a similar pattern of brain response where the Joe face elicited a significantly larger P300 amplitude than the Other and Bob face. In the Bob half of the experiment, the Bob face elicited a reliably larger P300 than the Other faces
and the heightened P300 to the Joe face was sustained. In Experiment 2, we examined whether the increased N2S0 negativity and enhanced P300 to Joe was due to simple naming effects. Participants were introduced to both Joe and Bob faces and names at the beginning of the experiment. During the first half of the experiment,
participants were to monitor for the Joe face and at the half-way point, they were instructed to switch targets to the Bob face. Findings show that N250 negativity significantly increased to the Joe face relative to the Bob and Other faces in the first half of the experiment and an increased N250 negativity was found for target Bob face and the non-target Joe face in the second half. An increased P300 amplitude was demonstrated to the target Joe and Bob faces in the first and second halves of the experiment, respectively. Importantly, the P300 amplitude elicited by the Joe face equaled the P300 amplitude to the Bob face even though it was no longer the target face.The findings from Experiment 1 and 2 suggest that the N250 component is not solely determined
by name labeling, exposure or task-relevancy, but it is the combination of these factors that contribute to the acquisition of enduring face representations.

These two studies focused on the development of infants’ functional body knowledge. Many aspects of infant body knowledge have been researched extensively. For example, body parts are mapped onto the somatosensory cortex at least coarsely in infants as young as a few days old or older (Le Cornu Knight, Cowie, & Bremner, 2016; Milh et al., 2007). Infants also have some integration of sensory inputs and motor outputs, as evidenced by their ability to look toward the source of a sound during the first half-year of life (Ashmead, Davis, Whalen, & Odom, 1991; Morrongiello, Fenwick, Hillier, & Chance, 1994). Additionally, infants have some knowledge of body structure, as they can detect discrepancies in the arrangement of the configuration of these body parts and distortions in body part size as early as 3.5 months of age (Zieber, Kangas, Hock, & Bhatt, 2015). Most previous research has focused on nervous system structure, knowledge of body structure, or reactive responses to the environment. Less is known about the development of the agentive response of infants localizing targets on their bodies. In a longitudinal study, vibrating targets were placed on eight different face locations approximately every other week starting as young as 2 months of age to test the development of infants’ ability to reach to targets on the surface of the body. The primary findings were that the ability to reach to targets on the face improved with age, and infants could reach to the mouth earlier than the other face locations. In a second study, these infants then received additional experience with a visual-proprioceptive-tactile contingency in the mirror, which accelerated mirror self-recognition relative to two control group.

▼ Recognizing the content of human actions is an
important skill in our adaptation to the environment. We rely on
our visual system to constantly interpret the actions, intentions,
physical and emotional states of the people around us. In this
work, we provide a computational investigation of the visual
representations that enable the visual system to decode this rich
modality of information. Using biological motion as the starting
point, we investigated the role of mid-level motion, disparity and
form cues in biological motion and action
recognition at large. The
joint representations of motion and disparity seem to approximate
the selectivity properties of primate medial temporal area cells.
When we evaluated the mid-level visual features in an action
recognition task, we found that the form cue carries sufficient
diagnostic information for actions performed by realistic actors.
However, form cues fail drastically for point-light displays where
the actor composed of 10-12 moving markers. Our results suggest
that learning the correspondence between motion and disparity might
cues explain how people can readily recognize the actions shown in
point-light displays without any training. Reflecting human
psychophysics performance, the correspondence between motion and
disparity also provides insight on how people perceive the
under-constrained, ambiguous depth structure in point-light
displays as a congruent figure. In conclusion, we reason that the
joint learning of motion and disparity can be the basis of
structural representations used in action
recognition.

▼ The representational format and the specific feature
codes used by face processing are key issues in the study of both
human and automatic face
recognition. The work described in this
dissertation explores these issues using a combination of
behavioral testing, neuroimaging (fMRI), computational modeling and
image analysis. The core idea of this work is that systems for
automatic
recognition can serve as models and as test beds for
computational accounts of human face processing at both the
behavioral and neural levels. The first study describes a method
for human-guided facial feature segmentation that allows one to
make explicit the part-whole structure of faces and removes a
priori assumptions concerning the way faces should be divided into
parts. The study examines the utility and the psychological
plausibility of this format by applying it to the task of facial
gender
recognition. The second study explores a representational
format that uses image fragments to encode object category and
applies it to the study of two
recognition tasks: detection and
identification. Within this framework, we assess the extent to
which diagnosticity with respect to the two tasks differs across
image fragments. Based on objective differences we find between
task-specific representations, we test and confirm the sensitivity
of the human visual system to these different face descriptions
independently of one another. Finally, the third study examines the
possibility of deriving feature codes for face detection directly
from the pattern of behavioral / neural responses elicited by noise
fields. The results converge on a coarse but robust visual
structure highly diagnostic for face detection. In sum, our present
work explores region-based visual representations for face
processing. We argue for the value of these representational
formats based on both computational performance and empirical
evidence.

▼ What action or actions does a person perform when she
recognizes someone? I argue she engages in a process composed of
four parts. First, she attends to the
subject in a particular
manner. Second, she uses the information gathered in the first
stage to categorize the
subject. Third, she appreciates the import
or significance of the
subject in light of the category she
employs. Fourth, she acknowledges the
subject by engaging the
subject’s attention as one who bears that import and that category.
My analysis helps us interpret theories of
recognition. One
clarifies a theory’s specific claims by decomposing theories into
instances of recognizing and then further analyzing each instance
into discrete actions. First one determines how many instances of
the process are involved by stating who does what to whom and for
what end. Once instances are separated, one analyses each instance
into its four components by describing the agent’s progress through
the process of recognizing. The final result is an organizing body
of specific claims with well-defined relations to one
another.

▼ Emotion is a state that comprehensively represents human feeling, thought and behavior, thus takes an important role in interpersonal human communication. Emotion estimation aims to automatically discriminate different emotional states by using physiological and nonphysiological signals acquired from human to achieve effective communication and interaction between human and machines. Brainwaves-Based Emotion Estimation is one of the most common used and efficient methods for emotion estimation research. The technology reveals a great role for human emotional disorder treatment, brain computer interface for disabilities, entertainment and many other research areas. In this thesis, various methods, schemes and frameworks are presented for Electroencephalogram (EEG) based human emotion estimation. Firstly, a hybrid dimension feature reduction scheme is presented using a total of 14 different features extracted from EEG recordings. The scheme combines these distinct features in the feature space using both supervised and unsupervised feature selection processes. Maximum Relevance Minimum Redundancy (mRMR) is applied to re-order the combined features into max-relevance with the emotion labels and min-redundancy of each feature. The generated features are further reduced with Principal Component Analysis (PCA) for extracting the principal components. Experimental results show that the proposed work outperforms the state-of-art methods using the same settings at the publicly available Database for Emotional Analysis using Physiological Signals (DEAP) data set. Secondly, a disentangled adaptive noise learning β-Variational autoencoder (VAE) combine with long short term memory (LSTM) model was proposed for the emotion recognition based on EEG recordings. The experiment is also based on the EEG emotion public DEAP dataset. At first, the EEG time-series data are transformed into the Video-like EEG image data through the Azimuthal Equidistant Projection (AEP) to original EEG-sensor 3-D coordinates to perform 2-D projected locations of electrodes. Then Clough-Tocher scheme is applied for interpolating the scattered power measurements over the scalp and for estimating the values in-between the electrodes over a 32x32 mesh. After that, the βVAE LSTM algorithm is used to estimate the accuracy of the quadratic (arousal-valence) classification. The comparison between the β VAE-LSTM model and other classic methods is conducted at the same experimental setting that shows that the proposed model is effective. Finally, a novel real-time emotion detection system based on the EEG signals from a portable headband was presented, integrated into the interactive film 'RIOT'. At first, the requirement of the interactive film was collected and the protocol for data collection using a portable EEG sensor (Emotiv Epoc) was designed. Then, a portable EEG emotion database (PEED) is built from 10 participants with the emotion labels using both self-reporting and video annotation tools. After that, various feature extraction, feature selection,…

▼ Real-time control of visual display systems via
mid-air hand gestures offers many advantages over traditional
interaction modalities. In medicine, for example, it allows a
practitioner to adjust display values, e.g. contrast or zoom, on a
medical visualization interface without the need to re-sterilize
the interface. However, there are many practical challenges that
make such interfaces non-robust including poor tracking due to
frequent occlusion of fingers, interference from hand-held objects,
and complex interfaces that are difficult for users to learn to use
efficiently. In this work, various techniques are explored for
improving the robustness of computer interfaces that use hand
gestures. This work is focused predominately on real-time
markerless Computer Vision (CV) based tracking methods with an
emphasis on systems with high sampling rates. First, we explore a
novel approach to increase hand pose estimation accuracy from
multiple sensors at high sampling rates in real-time. This approach
is achieved through an intelligent analysis of pose estimations
from multiple sensors in a way that is highly scalable because raw
image data is not transmitted between devices. Experimental results
demonstrate that our proposed technique significantly improves the
pose estimation accuracy while still maintaining the ability to
capture individual hand poses at over 120 frames per second. Next,
we explore techniques for improving pose estimation for the
purposes of gesture recognition in situations where only a single
sensor is used at high sampling rates without image data. In this
situation, we demonstrate an approach where a combination of
kinematic constraints and computed heuristics are used to estimate
occluded keypoints to produce a partial pose estimation of a user's
hand which is then used with our gestures recognition system to
control a display. The results of our user study demonstrate that
the proposed algorithm significantly improves the gesture
recognition rate of the setup. We then explore gesture interface
designs for situations where the user may (or may not) have a large
portion of their hand occluded by a hand-held tool while gesturing.
We address this challenge by developing a novel interface that uses
a single set of gestures designed to be equally effective for
fingers and hand-held tools without the need for any markers. The
effectiveness of our approach is validated through a user study on
a group of people given the task of adjusting parameters on a
medical image display. Finally, we examine improving the efficiency
of training for our interfaces by automatically assessing key user
performance metrics (such as dexterity and confidence), and
adapting the interface accordingly to reduce user frustration. We
achieve this through a framework that uses Bayesian networks to
estimate values for abstract hidden variables in our user model,
based on analysis of data recorded from the user during operation
of our system.

▼ This thesis explores the role of gist memory and gist representation in the formation of false recognition, specifically in the Deese, Roediger and McDermott Paradigm. We found that normal individuals displayed a range of susceptibility to false recognition and true recognition and this was related to their scores on both the Autism Spectrum Quotient and the Toronto-Alexithymia Scale. More ‘male-brained’ participants exhibited less susceptibility to false recognition but also less veridical recognition. The reverse was true for more ‘female-brained’ participants. The idea of false recognition and gist memory lying along a continuum was further emphasised by work on individuals with Autism Spectrum Disorder. We found they were less susceptible to false recognition but also produced less veridical recognition. We also found differences in performance between two groups of autism individuals who also differed in age. The results of further manipulations using both picture and word paradigms suggested that gist memory could be improved in younger individuals with autism. We also examined a patient group with Functional Memory Disorder using the DRM paradigm and a confabulation task and found them less able to produce true recognition in the DRM compared with a control group. Their memory impairments could not be attributed to depression since none were clinically depressed, so we suggested that they represent the tale end of impairment to gist memory. We also explored gist memory in a patient with dense anterograde amnesia who showed reduced true recognition and a tendency to reduced false recognition, but through manipulation of the stimuli using word and pictorial material she could perform like controls due to improved item-specific discrimination. A new face recognition paradigm was also tested in which she showed a tendency towards increased false recognition in comparison with controls. Finally, we suggest the use of the DRM paradigm as a test for memory malingering since we found participants could not replicate the performance of amnesia patients without a cost in their response latencies. This is discussed through the case study of GC a man suspected of exaggerating his memory symptoms.

▼ Automated
recognition of object categories in images is a critical step for many real-world computer vision applications. Interest region detectors and region descriptors have been widely employed to tackle the variability of objects in pose, scale, lighting, texture, color, and so on. Different types of object
recognition problems usually require different image features and corresponding learning algorithms. This dissertation focuses on the design, evaluation and application of new image features and learning algorithms for the
recognition of biological, generic and social objects. The first part of the dissertation introduces a new structure-based interest region detector called the principal curvature-based region detector (PCBR) which detects stable watershed regions that are robust to local intensity perturbations. This detector is specifically designed for region detection for biological objects. Several
recognition architectures are then developed that fuse visual information from disparate types of image features for the categorization of complex objects. The described image features and learning algorithms achieve excellent performance on the difficult stonefly larvae dataset. The second part of the dissertation presents studies of methods for visual codebook learning and their application to object
recognition. The dissertation first introduces the methodology and application of generative visual codebooks for stonefly
recognition and introduces a discriminative evaluation methodology based on a maximum mutual information criterion. Then a new generative/discriminative visual codebook learning algorithm, called iterative discriminative clustering (IDC), is presented that refines the centers and the shapes of the generative codewords for improved discriminative power. It is followed by a novel codebook learning algorithm that builds multiple codebooks that are non-redundant in discriminative power. All these visual codebook learning algorithms achieve high performance on both biological and generic object
recognition tasks. The final part of the dissertation describes a socially-driven clothes
recognition system for an intelligent fitting-room system. The dissertation presents the results of a user study to identify the key factors for clothes
recognition. It then describes learning algorithms for recognizing these key factors from clothes images using various image features. The clothes
recognition system successfully enables automated social fashion information retrieval for an enhanced clothes shopping experience.

▼ In this report, we first compare the novel RISq method to HMM. Both methods are used for the
recognition of general vector sequences. Our comparison shows that RISq performs better than HMM in many aspects. The training of RISq requires only one example from each class and the training is much simpler than training HMM models. Also a few sparse samples from a test sequence are usually sufficient for RISq to achieve robust
recognition while HMM needs the entire sequence. This makes RISq essentially much less sensitive to missing vectors. Lastly, our experiments demonstrate that RISq outperforms HMM in term of handling large sets of models or with many vectors dimensions. RISq is also better in noise robustness, computation time, selectivity ratio, etc.
For human gesture
recognition, we develop a novel system to recognize different hand gestures. We use an Inertial Measurement Unit equipped with accelerometers and gyroscopes to sense the motion of the operator's hand. The IMU is calibrated with the help of Nonlinear Data-Fitting method. Gesture trajectories are reconstructed from inertial sensor measurements using the Inertial Navigation System theory. We develop a novel method named Zero Velocity Linear Compensation (ZVLC) to improve trajectory reconstruction accuracy. Experimental results show that ZVLC provides more accurate reconstruction than the widely used method of Zero Velocity Compensation. At the
recognition stage, the novel RISq method is employed to recognize the reconstructed gesture trajectories and achieves a
recognition rate of 92%.
In the third part of this thesis, we describe a novel method for 3D head reconstruction and view-invariant
recognition, which is based on Shape From Shading combined with Hybrid Principal Component Analysis (HPCA). Our novel HPCA algorithm provides good initial estimates of 3D range mapping for the SFS optimization and yields much improved 3D reconstruction. Additional contribution of our chapter is the successful handling of variable and unknown surface albedo in SFS. Experimental results show that our HPCA based SFS method provides accurate 3D head reconstructions and high
recognition rates. Our work could have many practical applications such as person
recognition from side views when only frontal views are available for modeling.

▼ Finger gesture
recognition using glove-like interfaces are very accurate for sensing individual finger positions by employing a gamut of sensors. However, for the same reason, they are also very costly, cumbersome and unaesthetic for use in artistic scenarios such as gesture based music composition platforms like Virginia Tech's Linux Laptop Orchestra. Wearable computing has shown promising results in increasing portability as well as enhancing proprioceptive perception of the wearers' body. In this thesis, we present the proof-of-concept for designing a novel muscle-machine interface for interpreting human thumb motion as a 2-dimensional joystick employing mechanomyographic signals. Infrared camera based systems such as Microsoft Digits and ultrasound sensor based systems such as Chirp Microsystems' Chirp gesture recognizers are elegant solutions, but have line-of-sight sensing limitations. Here, we present a low-cost and wearable joystick designed as a wristband which captures muscle sounds, also called mechanomyographic signals. The interface learns from user's thumb gestures and finally interprets these motions as one of the four kinds of thumb movements. We obtained an overall classification accuracy of 81.5% for all motions and 90.5% on a modified metric. Results obtained from the user study indicate that mechanomyography based wearable thumb-joystick is a feasible design idea worthy of further study.

▼ The goal of this research is to improve a system capable to detect, track a single person and recognize poses real time for controlling a spatial game. After performing background subtraction, the human blob is segmented in order to track the torso and hands. Angles and distances between hands and torso center are used to compute the features. Finally, a 10-Nearest-Neighbor classifier recognizes 9 predefined Poses which are used by the player to control the game. This work contributes with two improvements. The first one is a more robust improved hand detection combining the current skin color detection with human blob information. The second improvement is a classifier that recognizes Non-Poses in addition to the 9 predefined Poses that are used in the game.

▼ This thesis presents techniques for locating landmarks in images of human faces. A modified Active Shape Model (ASM [21]) is introduced that uses a form of SIFT descriptors [68]. Multivariate Adaptive Regression Splines (MARS [40]) are used to efficiently match descriptors around landmarks. This modified ASM is fast and performs well on frontal faces. The model is then extended to also handle non-frontal faces. This is done by first estimating the face's pose, rotating the face upright, then applying one of three ASM submodels specialized for frontal, left, or right three-quarter views. The multiview model is shown to be effective on a variety of datasets.

▼ There has been a growing interest in machine-based recognition of emotions from body gait and posture, and its combination with other modalities. Applications such as human computer interaction, social robotics, and security have been the driving force behind such trend. The majority of the previous work in automatic affect perception deploys only either local features or global features. Whilst a combination of both types of features are deployed in applications such as object recognition and facial recognition, the literature does not reveal any study in affect recognition from body language using combined global and local features. In this thesis, such gap is addressed by examining how deploying a combination of local and global features can improve the recognition rate in automatic classification of emotions using gait and posture.
The motion data used in the study comprising kinematic parameters associated with the gait and posture of a number of actors expressing a set of emotions, were recorded electronically using an inertia motion capture system. A combination of local and global features proposed by Kapur et al. and Zacharatos et al., respectively, were used in the classification process using WEKA classification system. Additional global features of shape flow and shaping, horizontal and vertical symmetry were added to the combination feature set to increase the performance of the classifier.
The results obtained in the analysis demonstrate that deploying a combination of local and global features leads to a more robust and reliable method for automatic affect recognition from body language as it improves accuracy across a range of classifiers. This research also demonstrates that the inclusion of the additional features, which represent additional Laban Movement Analysis components, increases the maximum classification accuracy from 88.5% to 92.3%.
Achieving better automatic affect recognition rates can lead to increased application of the approach, improved usefulness and reliability of such systems.

▼ Dynamic scene understanding requires learning representations of the components of the scene including objects, environments, actions and events. Complex activity
recognition
from images and videos requires annotating large datasets with action labels which is a tedious and expensive task. Thus, there is a need to design a mid-level or intermediate
feature representation which does not require millions of labels, yet is able to generalize to semantic-level
recognition of activities in visual data. This thesis makes three contributions
in this regard. First, we propose an event concept-based intermediate representation which learns concepts via the Web and uses this representation to identify events even with a single labeled example. To demonstrate the strength of the proposed approaches, we contribute two diverse social event datasets to the community. We then present a use case of event concepts as a mid-level representation that generalizes to sentiment
recognition in diverse social
event images. Second, we propose to train Generative Adversarial Networks (GANs) with video frames (which does not require labels), use the trained discriminator from GANs as an
intermediate representation and finetune it on a smaller labeled video activity dataset to recognize actions in videos. This unsupervised pre-training step avoids any manual feature
engineering, video frame encoding or searching for the best video frame sampling technique. Our third contribution is a self-supervised learning approach on videos that exploits both spatial and temporal coherency to learn feature representations on video data without
any supervision. We demonstrate the transfer learning capability of this model on smaller labeled datasets. We present comprehensive experimental analysis on the self-supervised
model to provide insights into the unsupervised pretraining paradigm and how it can help with activity
recognition on target datasets which the model has never seen during training.

▼ Human activity
recognition is an emerging area of research in computer vision with applications in video surveillance, human-computer interaction, robotics, and video annotation. Despite a number of recent advances, there are still many opportunities for new developments, especially in the area of person-person and person-object interaction. Many proposed algorithms focus on recognizing solely single person, person-person or person-object activities. An algorithm which can recognize all three types would be a significant step toward the real-world application of this technology.
This thesis investigates the design and implementation of such an algorithm. It utilizes background subtraction to extract the subjects in the scene, and pixel clustering to segment their image into body parts. A location-based feature identification algorithm extracts feature points from these segments and feeds them to a classifier which identifies videos as activities. Together these techniques comprise an algorithm that can recognize single person, person-person and person-object interactions. This algorithm's performance was evaluated based on interactions in a new video dataset, demonstrating the effectiveness of using limb-level feature points as a method of identifying human interactions.

▼ In this thesis, we explore the statistical and geometrical behavior of uncontrolled parameters of human face, including both rigid transform caused by head pose and non-rigid transform caused by facial expression. We focus on developing 3D facial
recognition schemes that can be robust for these uncontrolled parameters.
This thesis presents a novel 3D face
recognition method by means of the evolution of iso-geodesic distance curves. Specifically, the proposed method compares two neighboring iso-geodesic distance curves, and formalizes the evolution between them as a one-dimensional function, named evolution angle function, which is Euclidean invariant. The novelty of this paper consists in formalizing 3D face by an evolution angle functions, and in computing the distance between two faces by that of two functions. Experiments on Face
Recognition Grand Challenge (FRGC) ver2.0 shows that our approach works very well on neutral faces. By introducing a weight function, we also show a promising result on non-neutral face database.
A 3D surface segmentation scheme is developed to detect the partial similarity between facial images. The proposed algorithm is based on iterative closest point (ICP) algorithm, which uses mean square distance as the cost function and is not able to detect partial similarities. The presented thesis make an improvement of ICP algorithm by iteratively removing points contributing largest error, and the remaining area of surface can be shown to be the partial similarity between two surface

▼ This research focuses on iris recognition, the most accurate form of biometric identification. The robustness of iris recognition comes from the unique characteristics of the human, and the permanency of the iris texture as it is stable over human life, and the environmental effects cannot easily alter its shape. In most iris recognition systems, ideal image acquisition conditions are assumed. These conditions include a near infrared (NIR) light source to reveal the clear iris texture as well as look and stare constraints and close distance from the capturing device. However, the recognition accuracy of the-state-of-the-art systems decreases significantly when these constraints are relaxed. Recent advances have proposed different methods to process iris images captured in unconstrained environments. While these methods improve the accuracy of the original iris recognition system, they still have segmentation and feature selection problems, which results in high FRR (False Rejection Rate) and FAR (False Acceptance Rate) or in recognition failure. In the first part of this thesis, a novel segmentation algorithm for detecting the limbus and pupillary boundaries of human iris images with a quality assessment process is proposed. The algorithm first searches over the HSV colour space to detect the local maxima sclera region as it is the most easily distinguishable part of the human eye. The parameters from this stage are then used for eye area detection, upper/lower eyelid isolation and for rotation angle correction. The second step is the iris image quality assessment process, as the iris images captured under unconstrained conditions have heterogeneous characteristics. In addition, the probability of getting a mis-segmented sclera portion around the outer ring of the iris is very high, especially in the presence of reflection caused by a visible wavelength light source. Therefore, quality assessment procedures are applied for the classification of images from the first step into seven different categories based on the average of their RGB colour intensity. An appropriate filter is applied based on the detected quality. In the third step, a binarization process is applied to the detected eye portion from the first step for detecting the iris outer ring based on a threshold value defined on the basis of image quality from the second step. Finally, for the pupil area segmentation, the method searches over the HSV colour space for local minima pixels, as the pupil contains the darkest pixels in the human eye. In the second part, a novel discriminating feature extraction and selection based on the Curvelet transform are introduced. Most of the state-of-the-art iris recognition systems use the textural features extracted from the iris images. While these fine tiny features are very robust when extracted from high resolution clear images captured at very close distances, they show major weaknesses when extracted from degraded images captured over long distances. The use of the Curvelet transform to extract 2D geometrical…

▼ Current approaches to metonymy
recognition are mainly supervised, relying heavily on
the manual annotation of training and test data. This forms a considerable hindrance
to their application on a wider scale. This dissertation therefore aims to relieve the
knowledge acquisition bottleneck with respect to metonymy
recognition by examining
knowledge-lean approaches that reduce this need for human effort.
This investigation involves the study of three algorithms that constitute an entire spectrum
of machine learning approaches—unsupervised, supervised and semi-supervised
ones. Chapter 2 will discuss an unsupervised approach to metonymy
recognition, and
will show that promising results can be reached when the data are automatically annotated
with grammatical information. Although the robustness of these systems is
limited, they can serve as a pre-processing step for the selection of useful training data,
thereby reducing the workload for human annotators.
Chapter 3 will investigate memory-based learning, a “lazy” supervised algorithm. This
algorithm, which relies on an extremely simple learning stage, is able to replicate the
results of more complex systems. Yet, it will also become clear that the performance
of this algorithm, like that of others in the literature, depends heavily on grammatical
annotation.
Finally, chapter 4 will present a semi-supervised algorithm that produces very promising
results with only ten labelled training instances. In addition, it will be shown that
less than half of the training data from chapter 3 can lead to the same performance as
the entire set. Semantic information in particular will prove very useful in this respect.
In short, this dissertation presents experimental results which indicate that the knowledge
acquisition bottleneck in metonymy
recognition can be relieved with unsupervised
and semi-supervised methods. These approaches may make the extension of
current algorithms to a wide-scale metonymy resolution system a much more feasible
task.

▼ Dual process theories account for age-related changes in memory by proposing that old age is associated with deficits in recollection together with invariance in familiarity (DPHMA). The authors evaluated the DPHMA by examining recollection and familiarity estimates in young and older adults. The results of this study do not support either premise of the DPHMA: older adults were impaired in the familiarity component of
recognition memory, while performing similarly to the younger group in terms of recollection. A second goal within the study was to investigate correlations between recollection and familiarity estimates and scores on tests thought to rely on frontal and medial temporal lobe regions. The only correlation that arose was between recollection and a medial temporal lobe measure in the older group. Limitations of the literature are considered and it is suggested that future research should consider individual effects of aging on older adult brain function.

▼ Backgrounds: A large amount of research has been put into the investigation of the
discernable decline in older adults’ abilities to explicitly label the six basic emotion
facial expressions. However, very little consideration has been given to the reasons
behind the apparent lack of behavioural problems that this decline induces. One
possible explanation is a spared implicit pathway that allows for unaffected
expression
recognition in adults of all ages.
Aims: The study reported herein aimed firstly to replicate the previous findings that
older adults are poorer at labelling expressions than younger adults, and secondly to
discern whether older adults are comparable to younger adults when it comes to the
implicit
recognition of facial expressions.
Methods & Procedures: The performance of 20 younger adults (M = 21.3 years-old)
was compared with the performance of 20 older adults (M = 64.9 years-old) first on
an implicit expression matching task and then on a simple facial expression labelling
task.
Outcomes & Results: In terms of labelling, the older group performed at a lesser
standard than the younger group. Specifically older adults were significantly less
accurate at identifying sadness. In terms of the implicit matching task the older
participants were found to be comparable to the younger participants at matching
anger, disgust and sadness. This pattern has since been replicated.
Conclusions: Due to this established pattern of results it can be deduced that an
implicit pathway does exist which spares older adults’
recognition of certain
emotions. However this finding could be extended by further research.

▼ The majority of previous research into the relationship between emotion
recognition and healthy adult aging finds an age-related decline in facial emotion
recognition accuracy in individuals over 60. However, this apparent age-related decline in emotion
recognition accuracy is at odds with research in other areas. One possible explanation for this inconsistency is that experimental tasks of the majority of studies into emotion
recognition and healthy adult aging lack ecological validity and thus their findings are not applicable to real life. The current study, like only a few before, aims to explore the relationship between facial emotion
recognition and healthy adult aging with the use of more ecologically valid tasks. Emotion
recognition accuracy was assessed in 21 younger (19 – 25 years) and 19 older adults (60 – 87 years) on 3 tasks of lower ecologically validity involving the
recognition of a uni-modal emotional stimulus (e.g. faces only, voices only, or context only), and 3 tasks of higher ecologically validity involving facial emotion
recognition while multiple congruent stimuli were presented (e.g. faces x voices, faces x context, & faces x voices x context). The study found that older participants were worse at recognising emotion in 2 out of 3 lower ecologically valid tasks (e.g. faces and voices only). In contrast, no age differences were found in the 3 higher ecologically valid tasks and accuracy in both age groups increased. Facial emotion
recognition accuracy was highest on the faces x voices x context task with no significant difference between the faces x voices and faces x context tasks. The findings are discussed in relation to previous research into emotion
recognition and healthy adult aging, other psychological areas, and the real world implications of the current findings.
