Region Based Rate-Distortion Analysis for 3D Video Coding

In 3D video coding, to provide the high-quality interactive viewpoint video to audience, it is necessary to jointly optimize coding efficiency of color and depth images at a given bit-rates. In this paper, a region based distortion model is proposed to precisely estimate the error of synthesized virtual view. Furthermore, combined with the rate-distortion (R-D) model of color and depth images coding, an overall R-D model is built up for 3D video coding. Experimental results exhibit that the proposed approach can efficiently measure the R-D property of 3D video coding.
