摘要

本研究的背景是3D视频。从一系列多视图视频加深度(MVD)数据开始，提出的基于四元的表示以统一的方式考虑了不同的问题，如紧凑性、压缩和中间视图合成。该表示分为两步。首先，对深度图进行四叉树分解，提取一组三维四边形;其次，选择性地消除四分体，以减少访谈冗余，从而提供紧凑的表示。在两个真实序列上进行的实验表明，与单视图视频相比，该算法在渲染阶段的效果良好，且数据过载小。

Compact quad-based representation for 3D video

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.
