Un panorama des techniques de suivi visuel temps réel pour la réalité augmentée

Augmented Reality has now progressed to the point where real-time applications are being considered and needed. At the same time it is important that synthetic elements are rendered and aligned in the scene in an accurate and visually acceptable way. In order to address these issues, a real-time, robust and efficient tracking algorithm have to be considered. The tracking of objects in the scene...

Image structures: From augmented reality to image stylization. (Structure d'une image : de la réalité augmentée à la stylisation d'images)

In this thesis we consider in general image structures and more specifically, image gradients and contours. They have been proven useful in recent years for various computer graphics applications, such as Augmented Reality (AR), image and video stylization. The goal of analyzing image structures is to describe a high level understanding of image contents and to provide a powerful support to imp...

Référentiels Spatiaux des Tâches d'Interaction et Caractéristiques de l'Utilisateur influençant la Performance en Réalité Virtuelle

In virtual reality, to adapt interfaces to users, two dimensions must be studied: the task and the user. The first dimension deals with interaction tasks in virtual reality, more precisely manipulation and locomotion. The study and the comparison of spatial properties of virtual and real environments allow us to propose tasks hierarchical models which show problematical interaction situations f...
