▼ In this thesis, multiple ground target tracking algorithms are studied. From different aspects of the ground target tracking, three different types of tracking algorithms are proposed according to the specialties of the ground target motion and sensors employed. Firstly, the dependent target tracking for ground targets is studied. State dependency is a common assumption in traditional target tracking algorithms, while this may not be the true in ground target tracking as the motion of targets are constraint to certain path. To enhance the tracking algorithm for ground targets, starting with the dependency assumption, Markov Random Field (MRF) based Probabilistic Data Association (PDA) approach is derived to associate motion dependent targets. The driving behavior model is introduced to describe motion relationship among targets. The Posterior Cramer-Rao Lower Bound (PCRLB) is derived for this new motion model. Experiments and simulations show that the proposed algorithm can reduce the false associations and improve the predictions. Eventually, the proposed approach alleviates issues like the track impurity and coalescence problem and achieves better performance comparing to standard trackers assuming state independence. Ground target tracking using cameras is then studied. To build an efficient multi- target visual tracking algorithm, fast single target visual tracking is an important component. A novel visual tracking algorithm that has high speed and better or comparable performance to state-of-the-art trackers is proposed. The proposed approach solves the tracking task by using a mixed-motion proposal based particle filter with Ridge Regression observation likelihood calculation. This approach largely reduces the exhaustive searching in common state-of-art trackers while maintains efficient representation of the target appearance change. Experiments on 100 public benchmark videos, as well as a high frame rate benchmark, are carried out to compare the performance with the state-of-art published algorithms. The results of the experiment show the proposed tracker achieves good performance while beats other algorithms in speed with a large margin. The proposed visual target tracker is integrated into a new multiple ground tar- get tracking algorithm using a single camera. The multi-target tracker addresses the issues in the target detection, data association and track management aside from the single target tracker. A perspective aware detection algorithm utilizing the re- cent advanced Convolutional Neural Networks (CNN) based detector is proposed to detect multiple ground targets and alleviate the weakness of CNN detectors in detecting small objects. A hierarchical class tree based multi-class data association is presented to solve the multi-class association problem with potential misclassified detections. Track management is also improved utilizing the high efficiency detectors and a Support Vector Machine (SVM) based track deletion is proposed to correctly remove the dead tracks. Benchmarking is presented… Advisors/Committee Members: Kirubarajan, Thia, Electrical and Computer Engineering.

▼ The tracking of moving objects in video sequences, also known as visual tracking, involves the estimation of positions, and possibly velocities, of these objects. Visual tracking is an important research problem because of its many industrial, biomedical, and security applications. Significant progress has been made on this topic over the last few decades. However, the ability to track objects accurately in video sequences having challenging conditions and unexpected events, e.g., background motion, object shadow, objects with different sizes and contrasts, a sudden change in illumination, partial object camouflage, and low signal-to-noise ratio, remains an important research problem. To address such difficulties, we adopted a multi-scale Bayesian approach to develop robust multiple object trackers. We introduce a novel concept in the field of visual tracking by adaptively fusing tracking results obtained from a fixed or variable number of wavelet subbands, corresponding to different scene directions and object scales, of a given video frame. Previous approaches to visual tracking were based on using the full- resolution video frame or a smoothed version of it. These approaches have limitations that were overcome by our multi-scale approach that is described in detail in this thesis. This thesis describes the design and implementation of four novel multi-scale visual trackers that are based on particle filtering and the adaptive fusion of subband frames generated using wavelets. We evaluated the performance of our novel trackers using different video sequences from the CAVIAR and VISOR databases. Compared to a standard full-resolution particle filter-based tracker, and a single wavelet subband (LL)2 based tracker, our multi-scale trackers demonstrate significantly more accurate tracking performance, in addition to a reduction in average frame processing time.

▼ Location tracking is of paramount importance to many applications such as healthcare, retail and navigation. Outdoor tracking can be easily implemented using the Global Positioning System (GPS). However, indoor tracking has been a difficult problem to tackle because GPS requires the line of sight to the satellites and therefore it does not work well in indoor environments. In this thesis, a high-precision indoor tracking system is proposed to identify, locate and track a person in an indoor room at a low cost. The proposed tracking system consists of three components: StepscanTM tiles, RFID and Kalman-filter based prediction. The StepscanTM tiles can generate precise location information. However, using StepscanTM tiles only in an indoor tracking system is too expensive because the manufacturing cost of each StepscanTM tile is very high. In the proposed system, StepscanTM tiles are deployed to cover a part of the indoor floor while RFID provides a full coverage. The location information from StepscanTM tiles and RFID is then used as inputs for our innovative prediction algorithm based on the Kalman filter, which consequently generates high-precision tracking results. The performance of the proposed system is investigated through extensive simulations. Our simulation results indicate that the proposed system increases the capability to track and locate a person by at least 24% (more than 50% in some cases), with errors ranging from 2.5% to 15%. Furthermore, the proposed system helps to reduce the cost of indoor tracking significantly. In terms of the number of StepscanTM tiles deployed in the system, a reduction of 7 to 25 tiles can be achieved in the scenarios under investigation. In terms of monetary cost, 21,000 to 75,000 can be saved for an indoor tracking system considered in our research. Advisors/Committee Members: n/a (external-examiner), Dirk V.

▼ Significant progress in the biomedical field (including cancer research, immunology and drug discovery) has been fuelled by an improved understanding of cell function and structure. Modern microscopy and imaging techniques have enabled cell biologists to observe and record cell processes in detail, thus generating high volumes of imaging data. Meaningful conclusions can only be drawn from such big datasets using automated quantitative analysis. This thesis focuses on ways to automatically perform detection, segmentation, and tracking of cells or subcellular structures in time-lapse microscopy image sequences to facilitate efficient analysis of these datasets. Furthermore, a secondary purpose of the thesis deals with the lack of annotated data in the biomedical field. In order to achieve these goals, we propose the use of probabilistic tracking algorithms to accurately and robustly track either migrating cells or their internal structures. For example, focal adhesions moving inside a single migrating normal human epidermal keratinocyte. In particular, the use of the Interacting Multiple Model (IMM) algorithm is proposed given its ability to take into account several different motion models at every given time. Within this framework, we formulate the data association problem as two linear assignment problems and we experiment with first and second order interacting models, different state vector definitions and hard or soft estimation. Regarding detection and segmentation, we propose several convolutional neural network architectures to detect and segment cells. The proposed networks have the advantage of being able to learn with very limited and incomplete training data. Moreover, we present a U-Net based multi-task learning architecture for simultaneously segmenting and detecting cells. In summary, the main contributions of this thesis are a multitarget tracking framework for identical targets, a novel integrated framework for focal adhesion detection and tracking, a U-Net based cell detector, and a novel multi-task U-Net architecture for simultaneously localising and segmenting cells in phase-contrast microscopy images.

▼ Public schools are examining their policies and instructional practices to address the achievement gap exposed by the reporting requirements of NCLB (Wenglinski, 2004). As accountability measures and stakes rise, there is a call for an improved use ofscientific evidence to inform educational policymaking (Wiseman, 2010). In terms ofthe achievement gap, national studies at the secondary level show when students are grouped according to ability there is a rise in achievement inequality between the groups (Gamoran & Mare, 1989; Hoffer, 1992). The purpose ofthis study is to determine ifthere is a tangible, measurable academic benefit to homogeneously grouping high school honors English students in a diverse, suburban school district in Washington State. The following research question guided this study: To what extent, ifany, does ability grouping ofhigh achieving students defmed as 9th and 10th grade honors English students in a suburban Washington State school district, affect their performance on state and pre-college assessments ofreading and writing achievement when controlling for student mutable variables? The research design used a non-experimenta~ explanatory associational design. Student achievement measures were examined before, during, and after high school students were placed in either like-ability (homogeneous) or mixed-ability (heterogeneous) groups when receiving honors English instruction in both their 9th and 10th grade years. The findings ofthis study indicate that type ofgrouping is not always a significant contributor to students' scores on state and pre-college assessments ofreading and writing achievement. In models where grouping was a significant contributor, the favored grouping type was not homogeneous but heterogeneous grouping. Due to the relatively small sample size ofthis study, it is recommended that additional studies be done to answer the research question. This question is essential in our educational system's continued pursuit ofequality of educational outputs; or in other words, closing and eliminating the achievement gap. It is recommended that a larger-scale experimental, quantitative study be done to determine if the results of this study can be replicated.

▼ The traditional high concentrating photovoltaic systems have proved to be expensive as they use high grade silicon solar cells, highly specular reflecting materials and require tracking arrangements which are equally expensive. The problem of un-even illumination creates heat-sinks which have not been solved in high concentrating systems. This thesis addresses the problem of un-even illumination in low concentrating photovoltaic systems using low cost reflecting materials for low-cost electricity. The large module cells are replaced by small string modules and the highly specular materials are replaced with low-cost diffuse materials.Concentrating sunlight onto a solar module has an effect of hot-spot formation which reduces the fill factor and hence the efficiency of the photovoltaic system. To address this problem, diffuse reflectors with rolling marks either parallel or perpendicular to the plane of the module were tested in low Concentrating photovoltaic systems. The changes in the fill factor were monitored as different reflector materials were replaced within concentrator geometries. It was experimentally shown that diffuse reflectors gave better fill-factor than specular reflectors. It was further demonstrated that diffuse reflectors with rolling grooves aligned parallel to the plane of the module gave better fill-factor than diffuse reflectors with rolling grooves aligned perpendicular to the plane of the module surface. In particular, the power increased by a factor of 2 in all reflector materials studied but the drop in the fill factor was 28% for rolling marks parallel to the plane of the module as compared to 30% for rolling marks perpendicular to the plane of the module. The parallel rolling marks (horizontal grooves) gave improved fill factor. Probably the rolling marks scattered the solar flux within the concentrator geometry at large angles and hence evenly illuminated the solar cell module area. The vertical grooves on the other hand had low angle scattering of the solar flux and could not spread the solar flux along the plane of the module. The vertical orientation of the grooves had similar performance as specular reflectors. Furthermore, the performance of the CPC geometry with semi-diffuse aluminium foil was under estimated due to construction errors as compared with anodized aluminium which gave a better performance as it was used as the base material. It was also verified that anodized aluminium, miro and rolled aluminium foil respectively, were the best reflector materials that withstood the environmental conditions.However, due to its low cost, the rolled aluminium foil was preferred for use in low concentrating photovoltaic systems.

Target tracking refers to the process of estimating the state of a moving object from remote and noisy measurements. In this thesis we consider the Bayesian filtering framework to perform target tracking under nonlinear models, a target moving in continuous time, and measurements that are available in discrete time intervals (known as continuous-discrete). The Bayesian filtering theory establishes the mathematical basis to obtain the posterior probability density function of the state, given the measurement history. This probability density function contains all the information required about the state of the target. It is well documented that there is no exact solution for posterior density under the models mentioned. Hence, the approximation of such density functions have been studied for over four decades. The literature demonstrates that this has led to the development of multiple filters. In target tracking, due to the remote sensing performed, an additional complication emerges. The measurements received are not always from the desired target and could have originated from unknown sources, thus making the tracking more difficult. This problem is known as a measurement origin uncertainty. Additionally to the filters, different methods have been proposed to address the measurement origin uncertainty due to its negative impact, which could cause a false track. Unfortunately, a final solution has yet to be achieved. The first proposal of this thesis is a new approximate Bayesian filter for continuous-discrete systems. The new filter is a higher accuracy version of the cubature Kalman filter. This filter is developed using a fifth-degree spherical radial cubature rule and the Ito-Taylor expansion of order 1.5 for dealing with stochastic differential equations. The second proposal is an improved version of the probabilistic data association method. The proposed method utilizes the maximum likelihood values for selecting the measurements that are used for the data association. In the first experiment, the new filter is tested in a challenging 3-dimensional turn model, demonstrating superiority over other existing filters. In a second and third experiments, the proposed data association method is tested for target tracking in a 2-dimensional scenarios under heavy measurement origin uncertainty conditions. The second and third experiments demonstrate the superiority of the proposed data association method compared to the probabilistic data association.

▼ This research examines some design features that may increase noticeability, readership and recall of warnings within the text of product ownerÃ¢â‚¬â„¢s manuals. Variables manipulated were warning saliency (e.g., low or high saliency), the physical placement of warnings in text (e.g., embedded versus separate), and text-directed cueing (e.g., low versus high salient cueing) in a fractional factorial design. Warnings were made salient by adding signal word panel color, alert symbol icons, bulleted text and black borders. Low salient warnings lacked those features and the warning was given in paragraph prose-style text. Two conditions, a non-eye tracked and an eye-tracked, underwent similar procedures to assess reading and recall of the warning information. Six groups comprised the non-eye tracked sample: each group viewed a unique condition with a unique combination of warning features. The eye-tracked sample viewed 2 opposing conditions with warning feature combinations that comprised a low and high salient condition. While there were no significant group differences in warning information recall accuracy in the non-eye tracked samples, the low salient conditions in the eye-tracked samples had higher recall accuracy than the high salient conditions. Also, the high salient conditions with high salient cues, significantly shifted visual attention to cued warnings more often than the low salient conditions with low salient cues. However, the eye-tracked sample failed to show significance differences for noticing and reading between low and high salient conditions. In addition, the assessment of the first three fixations indicated that participants may initially scan page contents before reading onset at the top left corner of the page, however fixation locations were not influenced by warning locations. Future research directions and study implications are addressed. Advisors/Committee Members: Michael S. Wogalter, Committee Co-Chair (advisor), Eric N. Wiebe, Committee Co-Chair (advisor), Douglas J.

▼ This thesis explores how to use real-time stereo vision to detect, track, and identify people in a surveillance scenario. The introduction of stereo vision significantly impacts this traditional computer vision application, which is currently dominated by monocular sensors. The additional depth information provided by stereo vision brings the object detection, tracking, and identification problems from the 2-d image domain to the 3-d world domain. This translation results in dramatic performance improvements. To enable this approach, several problems need to be solved.First, the system must perform in real-time. Surveillance systems usually operate without interruption, 24 hours a day. If the incoming video cannot be processed in real-time, the unprocessed data accumulates and eventually overflows the storage system. In addition, surveillance systems often need to respond immediately to certain events which require prompt handling. This thesis proposes a GPGPU-based stereo algorithm to deliver real-time performance on fairly high resolution.Second, detecting objects from video data usually involves a background model which estimates the behavior of the background scene. In the case of a stereo camera, a model which combines both appearance and depth information is proposed. This new stereo-based background model not only detects foreground regions from dynamic and cluttered backgrounds, but also detects moving shadows with high confidence. Based on this enhanced background modeling, object detection and tracking are performed on a top-down plan-view map, through which the uncertainty due to occlusion is handled with ease.A new approach to identifying person is also proposed so that tracking and searching individuals in a sparsely deployed camera network is possible. This new approach is based on a selective collection of 3-d enhanced local image features detected from a certain object, along with an efficient representation of the spatial structure relations amongst those features. Compared to existing approaches, this approach shows significantly improved performance especially on objects with flexible structure. Finally, a multi-resolution object descriptor compression scheme offers a solution to the problem of scalability in the proposed people identification algorithm.

▼ In the field of complex fluid, such as emulsions, polymer, colloids or surfactant solutions, an interesting research process is to analysis their multiphase characters. The primary difference between fluids and solids is how they respond to the shear stress: Pure fluid, which is viscous, tends to dissipate the mechanical energy, whereas a solid, which is more likely to store the energy, is elastic. For materials like complex fluids, their viscoelastic characters, which vary with the frequency, let them both store and dissipate the energy. Those characters are represented as complex shear modulus G*(ω). The viscous component is the imaginary part of G*(ω), which is also called the loss modulus G’’(ω); the elastic component is the real part of G*(ω), which is also called the storage modulus G’(ω). Usually, a good rheology method is to apply an oscillatory shear strain with different frequencies. With a given angular speed and temperature, the torque required to rotate the plate contacting with the fluid is measured, and the storage and loss modulus from the shear stress are calculated from the torque. To use this method, a rotor is used to rotate the fluid at different frequencies, and we calculate the viscous and elastic modulus (G’ G’’). C. Wilhelm et al. tested two modulus of Laponite colloidal suspension in 2002. The thesis introduces a new method of testing visco-elastic of fluid in high frequency by using the microscope and high speed camera. To test the viscosity and elastic characters of a solution, particles are tracked to calculate the mean squared displacement(MSD), using Laplace transformation on MSD to have the viscous and elastic modulus. T.G. Mason et al. recorded MSD of 0.21µm polystyrene latex particles in 15% polyethylene oxide solution; they also tested the Diffusing wave spectroscopy(DWS) measurements on ethylene glycol solution with 0.21µm silica particles. For both experiments, they had the visco-elastic modulus at the highest frequency of 20Hz. G. D. Jay et al. tested 6 different kinds of fluid, including both Newtonian and non-Newtonian fluids. For complex fluid, the highest frequency of visco elastic modulus was 100Hz/ To calculate the MSD, a commonly using method for tracking particles is to calculate the displacement of two images. One particle on the first image is focused on, around which a searching area is defined. The closest particle inside the searching area in the following image is regarded as the same particle as the first one. When there are no particles in the searching area, it means that the particles disappear from the field of the microscope. With this result, we have the displacement of one time interval (the time between two neighboring images, and the displacement belongs to the same particle). Integrating the displacement for each particle, we have the displacement for larger time intervals. This method has a good tracking result for large particles and low frequency. On one hand, the random walk for large particles is small, which is easy to be defined as correlated… Advisors/Committee Members: Breuer, Kenneth (Advisor).

▼ Multi-target tracking is a problem that involves estimating target states from noisy data whilst simultaneously deciding which measurement was produced by each target. The Probabilistic Multi-Hypothesis Tracker (PMHT) is an algorithmthat solves the multi-target tracking problem. This thesis presents extensions to the PMHT to address problems that may arise in the use of real sensors and considers multi-target tracking techniques for use in other applications such as autonomous vehicles. It is generally assumed that a sensor collects a set of noisy position measurements at known times. In some situations, the time information may not be reliable and cause filtering issues. This thesis derives an extension to the PMHT that introduces an assignment index that identifies the true time at which a measurement was collected. This extension of the PMHT allows for tracking on measurements with time errors, such as time delays. A further extension allows the PMHT algorithm to simultaneously estimate the time error parameters whilst tracking targets. The above extension is applied to the problem of planning paths for multiple platforms to explore an unknown area. Given a set of locales to be visited and the platform initial positions, the path planning problem has the same mathematical form as a multi-target tracking problem, with locales as measurements and the platforms as targets. The extended PMHT algorithm uses hypothesised time-stamps to associate locales to platforms and times simultaneously. Autonomous vehicles are expected to use information from their sensors to navigate and map their environment. Simultaneous localisation and mapping (SLAM) is the name given to this task and is essentially a multi-target tracking problem. This thesis proposes the use of PMHT and landmark classification information received with measurements to improve the performance of SLAM.

▼ Les glossines (Diptera, Glossinidae) constituent 31 espèces et sous-espèces réparties en trois sous-genres. Elles sont actuellement limitées à l’Afrique sub-saharienne et préfèrent trois habitats: la savane, les zones riveraines et la forêt. Les deux sexes sont strictement hématophages et peuvent transmettre la trypanosomiase au cours de leur repas de sang qui provoque la maladie du sommeil chez les humains et le nagana chez des animaux. Environ 60 millions de personnes et 50 millions de bovins dans 20 pays africains risquent continuellement l’infection, ce qui provoque des pertes économiques énormes. Les mouches tsé-tsé détectent les hôtes à proximité à l’aide de repères visuels, dont le contraste, la forme et la couleur, et de signaux olfactifs à distance. Comme elles sont ovovivipares, la dynamique de population des mouches tsé-tsé est caractérisée par un taux de croissance faible. Des pièges et cibles appâtés peuvent ainsi épuiser une population en quelques années seulement. Les stimulants olfactifs principalement utilisés dans les pièges sur le terrain contre les mouches tsé-tsé sont l’1-octène-3-ol, le 3-n-propylephénol, le p-crésol et de l’acétone. Les plantes fournissent aux mouches tsé-tsé non seulement habitat et refuge, mais en plus elles offrent des endroits protégés du soleil pour la larviposition aux femelles. La faculté naturelle des mouches pour trouver une couverture adaptée sous la végétation n’a attiré que peu d’attention. Tenant compte du rôle des sites de repos péridomestiques, il est important de considérer les produits chimiques volatils dérivés de plantes pour le développement de nouveaux pièges appâtés pour attirer toutes les tsé-tsé des 3 sous-genres. Il est possible que les mouches tsé-tsé font un usage parcimonieux de chimiostimuli (par exemple 1-octène-3-ol qui est présent dans les odeurs d’hôte autant que les substances volatiles de plantes) pour trouver hôte ou abris sous les plantes. En utilisant l’electroantennographie, les réponses sensorielles aux produits volatils couramment trouvés dans les plantes ainsi qu’aux odeurs d’hôtes ont été enregistrées chez des mouches tsé-tsé des trois habitats africains. Les produits comprennent des monoterpènes, des sesquiterpènes et des C6-alcohols et aldehydes (GLVs). Nous avons démontré que les espèces de glossines des trois habitats africains perçoivent les composants végétaux volatils d’une manière similaire, dont plusieurs à des seuils de détection similaires à l’1-octène-3-ol. Pour les études comportementales, la L-térébenthine est particulièrement interéssante, car il s’agit d’un mélange de terpènes simples avec un seuil de détection bas, avec le limonène et l’α-pinène comme composants principaux, accompagnés de monoterpène ocimène et d’aromatiques p-cymène. La L-térébenthine est relativement facile à obtenir, peu coûteuse et peut être produite directement en Afrique. Les mouches tsé-tsé ayant un vol rapide, nous avons filmé les réactions des G. pallidipes, G. brevipalpis et G.… Advisors/Committee Members: Patrick (Dir.).

▼ Nowadays, biologists and social scientists are interested in understanding fundamental evolutionary, ecological, and population processes, such as decision making and activity recognition in a group of individuals. Collective behavior of animals like fish or birds is governed by local mathematical rules. However, discovering the rules and the dynamics in more complex societies requires a different approach. In this thesis research work, I developed a sensor system to remotely extract data from social wild animals. The system is currently designed for Olive baboons, which have been our target species for this stage of the project. The system is composed of a main sensor unit which is located in a collar for and at least one secondary unit that we designed as a bracelet. The main unit is composed of a GPS, a 9 axis IMU and a microphone. It provides Wi-Fi and Bluetooth connectivity to allow the primary and secondary units to communicate, as well as to extract the data from the system remotely. We exploit the Bluetooth Low Energy to implement a proximity sensor. The secondary unit is equipped with a 6 axis IMU. The expected outcome of this project is a long-term deployment of the designed units on a troop of wild baboons in an uninstrumented environment. For this reason, the specifications for the device to be developed raised a set of new challenges to be addressed. Among them, the whole system will need to be tolerant of possible hardware faults while the energy consumption needs to be monitored and reduced as much as possible. The proposed work will allow scientists to have a deeper and more granular understanding of animal behavior on a long-term basis. The benefits of this setting will be empowering the scientific community with useful data and information to address animal conservation issues. Moreover, this technology could be adapted to other environments rather than the wild one, such as the possibility to study animals in agricultural, domestic, and habituated settings (such as zoos). This will make an impact on the productivity and efficiency of farms, veterinary health, and well-being of domesticated animals.

▼ The complex nature of the motion of maneuvering targets makes it difficult to accurately detect and track them, and estimate their states. In addition to this, fluctuating target returns and the increasing complexity and sophistication in electronic warfare systems introduce a great deal of false alarms in a cluttered environment thus making the task of tracking real targets more challenging. This dissertation investigates tracking techniques using different model sets and filters to track maneuvering targets in dense clutter.The Interacting Multiple Model (IMM) estimator is an algorithm that solves the maneuvering target tracking problem through the application of parallel filters that match a number of target models. This dissertation derives an extension to the interacting heterogeneous multiple model (IHMM) tracker that introduces the notion of target visibility to address instances when a target moves out of the surveillance region or being occluded by physical barriers or limitations of the sensor. This dissertation further investigates the comparative performance of feasible IHMM model sets to track maneuvering targets moving at different turning angles and acceleration. The target visibility concept is further applied in the context of IHMM tracker with global nearest neighbour technique to enhance multiple target tracking performance.This dissertation also investigates into the development of a classification capability that runs alongside the IHMM tracker in an automated surveillance system. The classification tool applied the principles of the Bayesian and Dempster-Shafer rules to classify tracks. Simulation results demonstrate the superior performance of our proposed and investigated enhancements to our surveillance system over the original system.The IHMM estimator with visibility is applied to target detection and tracking in a maritime surveillance scenario. The scenario involves aircraft detecting moving vessels in a maritime environment while a tracker stationed on a warship is monitoring the trajectory of the aircraft.

▼ The DLOOP is a structure of non-overlapping tiles (typically corner connected) occupying two layers. Interest in the DLOOP arises from Photo-Voltaic (PV) tracking applications. The tiles (PV modules) of contemporary tracking systems are within one contiguous layer, i.e. a side-by-side platform (SSP). Trees collect solar energy using branching structures to support leaves which are, similar to PV modules, planar surfaces of solar energy transformation. The tree's form is naturally excellent for lowering structural stress in limbs and thermal stress in leaves. For analogous reasons, related to the creation of flow paths that would otherwise be blocked, this research hypothesised (and has subsequently shown) that: * the fluid (wind) dynamic force on tiles of high inclination SSP may be reduced (up to 30%) adopting DLOOP arrangements; and * the temperature of heated tiles in SSP may be reduced (up to 5K within nominal and hot terrestrial environments), by passive convective cooling, adopting DLOOP arrangements. Fluid (wind) dynamic force is significant in PV applications because it typically exceeds the force of gravity on the tiles of SSP in 13m/s winds and increases with velocity squared. Hence reducing wind force by 30% should allow 40% more tiles to be fitted to contemporary tracking mechanisms. Temperature is significant in PV applications because the performance of PV tiles typically falls 0.4%/K. Hence a 5K reduction in temperature should improve efficiency 2%. A combination of wind-tunnel tests, Particle Image Velocimetry and Computational Fluid Dynamic (CFD) simulations using Reynolds Averaged Navier Stokes and Large Eddy Simulation turbulence models was used for the fluid dynamic research. A combined Finite Element/CFD simulation of PV panels in platforms was developed to model temperature outcomes of thermal diffusion in solid materials and thermal diffusion, radiation and convection in the fluid (air). If PV-tracking ranges are limited below those of the solar-vector, shading of the DLOOP lower by the upper layer occurs. This DLOOP self-shading raises unique cost-benefits associated with tracking ranges. Consequently, this research develops a means to quantify the insolation received by platforms accounting for technology and tracking range in diverse (Australian) climates. Additionally, multiple tracking platforms may be placed in close proximity and suffer "Parasitic" energy losses when shaded by self-similar neighbours. Therefore, this research study introduces a natural no-shade scale to describe and optimise field layouts according to local insolation and economic conditions.

▼ We present our work on multiple pedestrians tracking in a single camera and across multiple non-overlapping cameras. We propose an approach for online learning of discriminative appearance models for robust multi-target tracking in a crowded scene. Although much progress has been made in developing methods for optimal data association, there has been comparatively less work on the appearance model, which is the key element for good performance. Many previous methods either use simple features such as color histograms, or focus on the discriminability between a target and the background which do not resolve ambiguities between the different targets. We propose an algorithm for learning discriminative appearance models for different targets. Training samples are collected online from tracklets within a time sliding window based on some spatial-temporal constraints; this allows the models to adapt to target instances. Learning uses an AdaBoost algorithm that combines effective image descriptors and their corresponding similarity measurements. We term the learned models as OLDAMs. Our evaluations indicate that OLDAMs have significantly higher discrimination between different targets than conventional holistic color histograms, and when integrated into a hierarchical association framework, they help improve the tracking accuracy, particularly reducing the false alarms and identity switches. ❧ Furthermore, we extend our approach to multiple non-overlapping cameras. Given the multi-target tracking results in each camera, we propose a framework to associate those tracks. Collecting reliable training samples is a major challenge in on-line learning since supervised correspondence is not available at runtime. To alleviate the inevitable ambiguities in these samples, Multiple Instance Learning (MIL) is applied to learn an appearance affinity model which effectively combines three complementary image descriptors and their corresponding similarity measurements. Based on the spatial-temporal information and the proposed appearance affinity model, we present an improved inter-camera track association framework to solve the ""target handover"" problem across cameras. Our evaluations indicate that our method has higher discrimination between different targets than previous methods. Advisors/Committee Members: Nevatia, Ramakant (Committee Chair), Medioni, Gerard G. (Committee Member), Leahy, Richard M. (Committee Member).

▼ Augmented Reality (AR) is a technology that aims to embed virtual objects in the real world, showing to the user the set of objects (virtual and real) as a single world. For that purpose, it is necessary to offer a perfect alignment between virtual and real objects, which increases the effectiveness of AR. The solution to this problem is known as tracking. The object tracking consists in determining at any time the position and orientation of the camera relative to the scene. Optical sensors are most commonly used to overcome the tracking problem due to their low cost implementation. However, it is often difficult to provide robustness, accuracy and low computational cost at the same time. This thesis tackles the improvement and development of the main optical tracking techniques, primarily focused on detecting the deformations of the bodies. First, it has been achieved the tracking of rigid and non-rigid planar surfaces through a monocular camera, and then, the object deformation estimation with a more complex device as a RGB-D camera has been developed. Surface tracking systems such as those based on markers have the problem of not being able to handle occlusions. Thus, this thesis raises a new marker design that offers robustness against occlusions. Furthermore, in order to handle the deformations of surfaces, a solution that recovers the camera pose and the non-rigid surface simultaneously is proposed. Continuing with the deformation handling, it has also developed a robust tracking system for reconstructing the 3D shape of deformable objects using two different physical formulations. One offers a correct physical behaviour with a low computational cost, whereas the other achieves higher levels of accuracy at the expense of higher processing time. In addition, all the presented solutions have the common factor that all are executed in real time, which is a key property for a fluently visual feedback of an AR application.
