Description
Summary:The context of this study is 3D video. Starting from a sequence of multi-view video plus depth (MVD) data, the proposed quad-based representation takes into account, in a unified manner, different issues such as compactness, compression, and intermediate view synthesis. The representation is obtained into two steps. Firstly, a set of 3D quads is extracted by using a quadtree decomposition of the depth maps. Secondly, a selective elimination of the quads 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 and a small data overload compared to mono-view video.
