Abstract

Summary form only given. In 3D video (3DV), the virtual view images are commonly synthesized by the color and depth images of the reference views with image based rendering (IBR). Thus, in 3DV 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-rate by rate-distortion (R-D) property analysis of 3DV coding.to calculate E_dw, a region based distortion model is proposed firstly. In IBR, depth quantization error will cause the disparities between the pixels of the virtual view and the correspondent pixels of the reference views changed.
