Multi-Target Tracking with Probabilistic Graphical Models
Thanks to revolutionary developments in microscopy techniques such as robotic high-throughput setups or light sheet microscopy, vast amounts of data can be acquired at unprecedented temporal and spatial resolution. The mass of data naturally prohibits manual analysis, though, and life scientists thus have to rely more and more on automated cell tracking methods. However, automated cell tracking involves intricacies that are not commonly found in traditional tracking applications. For instance, cells may undergo mitosis, which results in variable numbers of tracking targets across successive frames. These difficulties have been addressed by tracking-by-assignment models in the past, which dissect the task into two stages, detection and tracking. However, as with every two-stage framework, the approach hinges on the quality of the first stage, and errors propagate partially irrevocably from the detection to the tracking phase.
The research in this thesis thus focuses on methods to advance tracking-by-assignment models in order to avoid these errors by exploiting synergy effects between the two (previously) separate stages. We propose two approaches, both in terms of probabilistic graphical models, which allow for information exchange between the detection and the tracking step to different degrees. The first algorithm, termed Conservation tracking, models both possible over- and undersegmentation errors and implements global consistency constraints in order to reidentify target identities even across occlusion or erroneous detections. Wrong detections from the first step can hence be corrected in the second stage. The second method goes one step further and optimizes the two stages completely jointly in one holistic model. In this way, the detection and tracking step can maximally benefit from each other and reach the overall most likely interpretation of the data. Both algorithms yield notable results which are state-of-the-art.
In spite of the distinguished results achieved with these methods, automated cell tracking methods are still error-prone and manual proof-reading is often unavoidable for life scientists. To avoid the time-consuming manual identification of errors on very large datasets, most ambiguous predictions ought to be detected automatically so that these can be corrected by a human expert with minimal effort. In response, we propose two easy-to-use methods to sample multiple solutions from a tracking-by-assignment graphical model and derive uncertainty measures from the variations across the samples. We showcase the usefulness for guided proof-reading on the cell tracking model proposed in this work.
Finally, the successful application of structured output learning algorithms to cell tracking in previous work inspired us to advance the state-of-the-art by an algorithm called Coulomb Structured Support Vector Machine (CSSVM). The CSSVM improves the expected generalization error for unseen test data by the training of multiple concurrent graphical models. Through the novel diversity encouraging term, motivated from experimental design, the ensemble of graphical models is learned to yield diverse predictions for test data. The best prediction amongst these models may then be selected by an oracle or with respect to a more complex loss. Experimental evaluation shows significantly better results than using only one model and achieves state-of-the-art performance on challenging computer vision tasks

Understanding video through the lens of language
The increasing abundance of video data online necessitates the development of systems capable of understanding such content. However, building these systems poses significant challenges, including the absence of scalable and robust supervision signals, computational complexity, and multimodal modelling. To address these issues, this thesis explores the role of language as a complementary learning signal for video, drawing inspiration from the success of self-supervised Large Language Models (LLMs) and image-language models.
First, joint video-language representations are examined under the text-to-video retrieval task. This includes the study of pre-extracted multimodal features, the influence of contextual information, joint end-to-end learning of both image and video representations, and various frame aggregation methods for long-form videos. In doing so, state-of-the-art performance is achieved across a range of established video-text benchmarks.
Second, this work explores the automatic generation of audio description (AD) – narrations describing the visual happenings in a video, for the benefit of visually impaired audiences. An LLM, prompted with multimodal information, including past predictions, and pretrained with partial data sources, is employed for the task. In the process, substantial advancements are achieved in the following areas: efficient speech transcription, long-form visual storytelling, referencing character names, and AD time-point prediction.
Finally, audiovisual behaviour recognition is applied to the field of wildlife conservation and ethology. The approach is used to analyse vast video archives of wild primates, revealing insights into individual and group behaviour variations, with the potential for monitoring the effects of human pressures on animal habitats
Critical Conversations with Suburban Administrative Leaders on Special Education Disproportionality: Case Studies of Suburban School Districts
This dissertation study explored high school administrators\u27 beliefs about why racial disproportionality exists, sought to understand the local practices that contribute to disproportionality, and identified interventions and supports that impact disproportionality in the special education referral, eligibility, and placement process. Research shows that students who are disproportionately represented in special education are negatively affected by factors such as stigmatization, substandard instruction, zero tolerance policies, and isolation from the general education setting (Sullivan, Kozleski, & Smith, 2008). Administrators were invited to participate in this study because they have a significant impact on student achievement and system-wide changes in schools.
This research study focused on three high schools in the suburbs of Chicago, Illinois. Three administrative leaders participated in a face-to-face semi-structured interview and completed a questionnaire via Opinio (ObjectPlanet, Inc, 2018). The Constant Comparative Method (Olson, McAllister, Grinnell, Walters, & Appunn, 2016) was utilized to perform data analysis and make meaning of administrators\u27 beliefs. Major themes emerged as to why racial disproportionality existed in their schools, which included sociodemographic factors, biases, and perceived student deficits by teachers. Three major themes emerged by administrators regarding the practices that contribute to racial disproportionality, which included absent school-wide systems, hopeless beliefs about student failure, and decisions affected by implicit bias. The heart of this qualitative study was to move beyond the causes, and to hear from local administrators which steps they will implement to address the unjust practices that contribute to disproportionality. Three major themes emerged for eliminating disproportionality, which included developing a systematic plan, collaborating with stakeholder groups, and increasing resources to help school personnel meet the needs of all students
Coopération de réseaux de caméras ambiantes et de vision embarquée sur robot mobile pour la surveillance de lieux publics
Actuellement, il y a une demande croissante pour le déploiement de robots mobile dans des lieux publics. Pour alimenter cette demande, plusieurs chercheurs ont déployé des systèmes robotiques de prototypes dans des lieux publics comme les hôpitaux, les supermarchés, les musées, et les environnements de bureau. Une principale préoccupation qui ne doit pas être négligé, comme des robots sortent de leur milieu industriel isolé et commencent à interagir avec les humains dans un espace de travail partagé, est une interaction sécuritaire. Pour un robot mobile à avoir un comportement interactif sécuritaire et acceptable - il a besoin de connaître la présence, la localisation et les mouvements de population à mieux comprendre et anticiper leurs intentions et leurs actions. Cette thèse vise à apporter une contribution dans ce sens en mettant l'accent sur les modalités de perception pour détecter et suivre les personnes à proximité d'un robot mobile. Comme une première contribution, cette thèse présente un système automatisé de détection des personnes visuel optimisé qui prend explicitement la demande de calcul prévue sur le robot en considération. Différentes expériences comparatives sont menées pour mettre clairement en évidence les améliorations de ce détecteur apporte à la table, y compris ses effets sur la réactivité du robot lors de missions en ligne. Dans un deuxiè contribution, la thèse propose et valide un cadre de coopération pour fusionner des informations depuis des caméras ambiant affixé au mur et de capteurs montés sur le robot mobile afin de mieux suivre les personnes dans le voisinage. La même structure est également validée par des données de fusion à partir des différents capteurs sur le robot mobile au cours de l'absence de perception externe. Enfin, nous démontrons les améliorations apportées par les modalités perceptives développés en les déployant sur notre plate-forme robotique et illustrant la capacité du robot à percevoir les gens dans les lieux publics supposés et respecter leur espace personnel pendant la navigation.This thesis deals with detection and tracking of people in a surveilled public place. It proposes to include a mobile robot in classical surveillance systems that are based on environment fixed sensors. The mobile robot brings about two important benefits: (1) it acts as a mobile sensor with perception capabilities, and (2) it can be used as means of action for service provision. In this context, as a first contribution, it presents an optimized visual people detector based on Binary Integer Programming that explicitly takes the computational demand stipulated into consideration. A set of homogeneous and heterogeneous pool of features are investigated under this framework, thoroughly tested and compared with the state-of-the-art detectors. The experimental results clearly highlight the improvements the different detectors learned with this framework bring to the table including its effect on the robot's reactivity during on-line missions. As a second contribution, the thesis proposes and validates a cooperative framework to fuse information from wall mounted cameras and sensors on the mobile robot to better track people in the vicinity. Finally, we demonstrate the improvements brought by the developed perceptual modalities by deploying them on our robotic platform and illustrating the robot's ability to perceive people in supposed public areas and respect their personal space during navigation

An Investigation Into Grouping Practices and Educational Trajectories Within a Year One Classroom
My research aimed to investigate learning in context by exploring the experiences of Year One children (aged 5 and 6 years old) within a single form entry Primary School in Sussex. The research uses an ethnographic case study approach and applies socio-cultural theoretical perspectives to attempt to understand some of the multifaceted influences that construct the cultural practices within the Year One class, with a particular focus on grouping practices and the repercussions of the children's differing experiences for acculturation within the school and the school system.
The data were collected over one academic year and comprised of documentation, field notes, a research diary, semi-structured interviews and classroom observations using video recording equipment. The ethnographic case study approach and data collection techniques were designed to accumulate detailed data which represented the cultural context, the individuals within it and their interactions during the class activities.
The research explores conceptions of 'ability' within the school and considers how the children's familiarity with school based practices and linguistic competences act to construct interpretations of their 'ability' which potentially enhances, or constrains, participation in school activity. The research foregrounds six focus children to explore their experiences, activity and interactions within the class, to construct an analysis of the class activity at different levels of social or cultural interaction and explicate some of the interplay between each, to attempt to understand learning in context.
The main themes from the analysis focus on notable differences between child-to-child interactions, adult-to-child interactions and learning opportunities across each of the 'ability' groups. The research considers how notions of ability act to structure children's experiences and subsequently influence identities, impact upon future activity and perpetuate inequalities
