Représentation compacte à base de quadrilatères pour la vidéo 3D Compact quad-based representation for 3D video

چکیده
The context of this study is 3D video. Starting from multiview video plus depth as input data, the goal of the proposed representation based on 3D polygons is to take into account in a unified manner different issues such as compactness, compression, and intermediate view synthesis. The method used to build such a representation is divided into two parts. First, a set of 3D polygons is obtained thanks to a quadtree decomposition of the depth maps. Polygons allow to deal with the problems identified in the state-ofthe-art section. In the second part, a selective elimination of the polygons is performed in order to reduce inter-view redundancies and thus provide a compact representation. Experiments on two real sequences show good quality results at the rendering stage for a small data overload compared to mono-view video.

La structuration automatique des grandes bases de données multimédia à partir du contenu non textuel a de nombreuses applications potentielles et permet de pallier à l’absence d’annotations riches et fiables. Dans le cas particulier des grandes bases vidéo, des liens très utiles entre séquences vidéo sont mis en évidence par la détection de copies par le contenu (DCPC). En simplifiant, on consi...

In this paper, we propose powerful virtual image processing tools (face cloning and video spatialization) which can be useful to design new teleconferencing systems offering a better comfort for users even if very low bit rate links are used. These tools allow a new teleconferencing concept, relying on the metaphor of a virtual meeting room where the participants can choose their position and p...

3D reconstruction of urban environments is a widely studied subject since several years, since it can lead to many useful applications : virtual navigation, augmented reality, architectural planification, etc. One of the most difficult problem nowadays in this context is acquisition and treatment of data if very large scale and precise reconstruction is aimed. In this paper we present a system ...
