Region-interior painting in Contour Based Depth map Coding System

Depth Image Based Rendering (DIBR) is a coding strategy for Multiview Video Coding (MVC). Depth video is involved to DIBR to represent another dimensional of the traditional 2D video (texture video). The physics meaning of depth video is different from texture video. But the traditional block based coding system use the same procedure to code both depth video and texture video. A new coding system that dedicate to depth video coding is proposed in this paper, which is called Contour Based Depth map Coding system (CBDC). To meet the feature of “sharp-edge” and “smooth-interior”, the proposed CBDC performs contour coding and interior coding separately. This paper focus on introduce the interior coding part. Linear painting modes and non-linear painting mode are introduced and compared. Experimental results indicate that proposed painting method performs an equivalent PSNR performance to the block based coding strategy (JMVC).
