Traitements vidéo et espaces virtuels de réunion

This paper describes video processing techniques developped in the context of a tele-virtuality project (project "TRAIVI"). This project intends to create and run virtual meeting places via low bit rate bindings. In this paper, preliminary results in cloning and video spatialization are described. The cloning of faces is realized by image processing and using a CYBERWARE model of the speaker for displaying. The video spatialization allows the reconstruction of some virtual points of view of the meeting room, by interpolating a set of three reference views.
