11-2 ボロノイ図に基づいた奥行きマップの領域分割符号化(第11部門立体映像技術)

抄録

Recently, the coding technology of multi-view video plus depth has been developed to implement 3D video applications such as Free Viewpoints Television. Because depth maps tend to have smooth value within an object and have strong edges between objects, it is efficient to encode depth maps by a region-oriented manner. In this paper, we introduce a segmentation method based on Voronoi diagrams to reduce the amount of information on the region shapes. Moreover, we propose a plane approximation to the depth values in each region.
