Abstract

As conventional video coding standards such as H.264, Multiview Video Coding (MVC) adopts a strategy of block based prediction toachieve high compression ratio (such as JMVC). In order to improve the coding efficiency of MVC system, Depth Image Based Rendering (DIBR) is proposed. Depth map is introduced to represent the information of another dimension. Comparing with texture map (2D), depth map indicates much more spatial continuity. In this work, Contour Based Depth map Coding (CBDC) is proposed to take the place of the conventional block based code structure. Framework of whole system is illustrated. Especially, details about the contour coding module are introduced in this paper. Experimental result shows that the bit cost of propose method (when DLP between 8 and 16) is equivalent toJMVC when QP between 12 and 16. Although the reconstructed frame lost some detail of texture in painting, the PSNR of synthesized view is competitive.
