A multi-view video coding approach using Layered Depth Image

Multi-view video introduces more forms of interactivity and can potentially be used for a variety of applications, such as free-view video (FVV) and three-dimensional video (3DTV). However, the huge volume video data and the synthesis of virtual view limit the practicality of multi-view video. In this paper, we propose an approach to multi-view video coding, in which the mutli-view video sequences are converted to layered depth images (LDIs) to represent scenes, and compressed layer by layer. To achieve better compression efficiency, we restructure layered images according depth data in LDIs. Experimental results show that our approach is practicable and efficient to meet the compression efficiency and flexible interactivity.
