Beaucoup d'applications en forte demande, telle que la surveillance pour la sécurité ou l'interaction homme-machine, profiteraient d'un système qui pourrait détecter et suivre automatiquement des humains. L'exécution de séquences de film réelles pose un défi particulier compte tenu de la non-rigidité du mouvement du corps humains, ainsi que l'influence qu'ont plusieurs facteurs sur son apparence. Parmi eux se trouvrent la différence dans la gamme de conditions d'acquisition, la variation de l'environnement et de l'illumination, le mouvement de caméra et le peu de connaissances a priori dans le positionnement de la caméra. En tant que complément à l'analyse du mouvement humain, ce système vise à aider son utilisateur à détecter de façon automatique le mouvement de la caméra, à diviser la séquence de film en petits segments appelés "prises de vue" et à extraire des informations du mouvement humain en présence d'un arrière-scène complexe. Pour atteindre cet objectif, une estimation précise du flux optique est employée. Un processus d'image par image peut identifier six différents mouvements de la caméra, incluant une camera statique, en utilisant des gabarits prédéterminés. Il peut ensuite fournir une base de données de mouvements de caméra pour la séquence du film. Ces données sont très utiles pour l'annotation, l'indexage et la recherche de séquences vidéos. De plus, une Mixture de Gaussiennes (MoG) dotée d'un espace de couleur RGB normalisé est utilisée pour soustraire un arrière-scène statique, qui permet d'éviter les effets d'ombres. Lors d'un mouvement de caméra, nous optons pour une technique appelée "codage de couleur" pour convertir les champs de vecteurs de mouvement en image colorée et appliquer la soustraction d'arrière-plan conventionnelle à cette image de flux optique de couleurs. Ceci dit, un système de suivi multicouches déployé dans deux directions (d'ordre chronologique et d'ordre anti-chronologique) est aussi décrit dans la thèse. Finalement, l'évaluation de la performance du système est réalisée sur plusieurs séquences extraites des films réels. Les séquences ont été entièrement analysées indépendamment par un observateur humain pour fournir une base de référence réelle sur les mouvements de caméra aussi bien que sur le mouvement humain dans les séquences vidéos. La comparaison entre les résultats et la base de référence indique une performance très prometteuse des approches proposées tant par l'analyse de films que par les applications de surveillance.

The review confines itself to the earlier stages of motion, focusing on tracking and motion synthesis. There is an extensive discussion of open issues. The authors identify some puzzling phenomena associated with the choice of human motion representation --- joint angles vs. joint positions. The review concludes with a quick guide to resources and an extensive bibliography of over 400 references. Computational Studies of Human Motion: Part 1, Tracking and Motion Synthesis is an invaluable reference for those engaged in computational geometry, computer graphics, image processing, imaging in general, and robotic.

Available in PDF, EPUB and Kindle. Book excerpt: As the general notion of cognition has recently broadened to include its embodied nature, researchers' accounts of perception have increasingly come to include the body's special status as a window on the world and to accommodate the specific perceptual requirements for identifying, interpreting, and interacting with other bodies. This volume presents a comprehensive overview of the rapid progress that has been made in understanding the human body and its relationship to perception. It will help to unify the relevant research from several independent areas of cognitive psychology and cognitive neuroscience and facilitate the development of an integrated framework for the study of human-body perception.

This book was released on 2012-12-06 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyzing Video Sequences of Multiple Humans: Tracking, Posture Estimation and Behavior Recognition describes some computer vision-based methods that analyze video sequences of humans. More specifically, methods for tracking multiple humans in a scene, estimating postures of a human body in 3D in real-time, and recognizing a person's behavior (gestures or activities) are discussed. For the tracking algorithm, the authors developed a non-synchronous method that tracks multiple persons by exploiting a Kalman filter that is applied to multiple video sequences. For estimating postures, an algorithm is presented that locates the significant points which determine postures of a human body, in 3D in real-time. Human activities are recognized from a video sequence by the HMM (Hidden Markov Models)-based method that the authors pioneered. The effectiveness of the three methods is shown by experimental results.

This book was released on 2016-04-11 with total page 1035 pages. Available in PDF, EPUB and Kindle. Book excerpt: Visual computing and descriptive geometry are multidisciplinary fields addressing the handling of images, 3D models, and other computer graphics. These ideas are experiencing a revival due to emergent technologies and applications available to developers. Based in traditional forms of design and architecture, these fields are currently experiencing a bounty of new research based on old principles. The Handbook of Research on Visual Computing and Emerging Geometrical Design Tools seeks to add to this knowledge base by considering these technologies from a designer’s perspective rather than reiterating the principles of computer science. It combines aspects of geometry and representation with emerging tools for CAD, generation, and visualization while addressing the digital heritage of such fields. This book is an invaluable resource for developers, students of both graphic and computer-generated design, researchers, and designers.
