Abstract:
With the introduction of Wireless Multimedia Sensor Networks, large-scale remote outdoor surveillance applications where the majority of the cameras will be battery-operated are envisioned. These are the applications where the frequency of incidents is too low to employ permanent staffing such as monitoring of land and marine border, critical infrastructures, bridges, water supplies, etc. Given the inexpensive costs of wireless resource constrained camera sensors, the size of these networks will be significantly larger than the traditional multi-camera systems.

Video sensor networks (VSNs) provide rich sensing information and coverage, both beneficial for applications requiring visual information such as smart homes, traffic control, healthcare systems and monitoring/surveillance systems. Since a VSN-based surveillance application is usually assumed to have limited resources, energy efficiency has become one of the most important design aspects of such networks. However, unlike common sensor network platforms, where power consumption mostly comes from the wireless transmission, the encoding process in a video sensor network contributes to a significa

Wireless multimedia sensor networks (WMSNs) are networks of interconnected devices that allow retrieving video and audio streams, still images, and scalar data from the environment. In a densely deployed WMSN, there exists correlation among the observations of camera sensors with overlapped coverage areas, which introduces substantial data redundancy in the network. In this dissertation, efficient communication schemes are designed for WMSNs by leveraging the correlation of visual information observed by camera sensors.

Deployment of cameras in Wireless Multimedia Sensor Networks (WMSNs) is crucial in achieving good coverage, accuracy and fault tolerance. With the decreased costs of wireless cameras, WMSNs provide opportunities for redundant camera deployment in order to get multiple disparate views of events.

In Wireless Multimedia Sensor Networks (WMSNs) the lifetime of battery operated visual nodes is limited by their energy consumption, which is proportional to the energy required for sensing, processing, and transmitting the data. The energy consumed in multimedia sensor nodes is much more than in the scalar sensors; a multimedia sensor captures images or acoustic signals containing a huge amount of data while in the scalar sensors a scalar value is measured (e.g., temperature).

Abstract:
Les réseaux de capteurs sans fil suscitent une attention croissante depuis quelques années, tant les applications sont nombreuses, incluant notamment le suivi de véhicules ou la surveillance de champs de bataille. Un ensemble de capteurs disséminé aléatoirement a pour but de surveiller des cibles se déplaçant dans une région donnée. Chaque capteur a une durée de vie limitée et deux états : actif ou inactif. Un capteur actif peut surveiller des cibles dans son rayon de portée, au prix d'une consommation d'énergie. Dans cette thèse, les problèmes étudiés consistent à déterminer un ordonnancement

Les progrès de la technologie des capteurs, des communications sans fil et de l'Internet des Objets ont favorisé le développement des réseaux de capteurs multimédias. Ces derniers sont composés de capteurs interconnectés capables de fournir de façon omniprésente un suivi fin d’un espace connecté. Grâce à leurs propriétés, les réseaux de capteurs multimédias ont suscité un intérêt croissant ces dernières années des secteurs académiques et industriels et ont été adoptés dans de nombreux domaines d'application (tels que la maison intelligente, le bureau intelligent, ou la ville intelligente).

Abstract:
Cette thèse porte sur la reconnaissance d'actions humaines dans des séquences vidéo RGB-D monoculaires. La question principale est, à partir d'une vidéo ou d'une séquence d'images donnée, de savoir comment reconnaître des actions particulières qui se produisent. Cette tâche est importante et est un défi majeur à cause d'un certain nombre de verrous scientifiques induits par la variabilité des conditions d'acquisition, comme l'éclairage, la position, l'orientation et le champ de vue de la caméra, ainsi que par la variabilité de la réalisation des actions, notamment de leur vitesse d'exécution.

Abstract:
Ce mémoire de thèse se place dans le contexte des applications de surveillance de l’environnement nécessitant des mesures régulières de caractéristiques biologiques ou géo-physiques. Il s’agit par exemple de mesurer la propagation de polluants dans les cours d’eau, de surveiller le développement de bactérie dans des eaux de baignade. Les réseaux de capteurs sans fils (RCsF) apparaissent comme des solutions économiques et fiables pour permettre l’automatisation de la collecte de telles données. Le bon fonctionnement de ces réseaux dépend de la qualité des transmissions radio, ce qui est particu

Abstract:
Aujourd'hui, la prolifération de matériel peu coûteux tels que les caméras et les microphones capables de capturer du contenu multimédia de façon ubiquitaire a conduit à l'émergence des réseaux de capteurs sans fil multimédia/vidéo (RCSFM /RCSFV). En conséquence, un grand éventail d'applications peuvent être projetées dans de nombreux domaines de la vie de tous les jours. Par rapport aux réseaux de capteurs traditionnels (RCSF), les RCSFVs présentent des défis uniques principalement en raison de la grande quantité de données à capturer et à transmettre au-dessus d'un réseau contraint en ressou

Les Réseaux de Capteurs Sans Fil (RCSFs) constituent une classe particulière des réseaux Ad hoc, faisant l'objet de recherches intensives. Ils sont considérés comme un outil très puissant pour connecter le monde physique et le monde numérique. Ils se composent d'un grand nombre de noeuds capteurs dotés de ressources limitées en termes d'énergie, de portée de capture et de communication, de vitesse de traitement et de capacité de stockage. Ils sont déployés dans un environnement intérieur ou extérieur, et ce dans de nombreux domaines d'application tels que l'armée, l'environnement, la santé, la

Les réseaux de capteurs sans fil (WSN) se composent de petits nœuds de capteurs dotés de microcontrôleurs intégrés, de radios à faible consommation, de batteries et de capteurs utilisés pour surveiller les conditions environnementales telles que la température, la pression, l'humidité et les vibrations. De nos jours, ces réseaux sont utilisés dans un large éventail d'applications militaires, sanitaires, domestiques, urbaines, industrielles et environnementales.
