Multiview video hybrid coding system with texture-depth synthesis

Multiview video coding (MVC) is getting more and more attention in recent years because of the realistic perception it can bring. However, the current H.264-based coding scheme cannot get enough coding gain in the rate-distortion (R-D) performance. Furthermore, the view synthesis and random access between views are also design challenges. In this paper, a multiview hybrid coding system with texture-depth synthesis is proposed. By sharing the prediction information between texture and depth maps, the depth map can be reconstructed with reduced bitrate overhead. Then, after using matrix-based warping and adaptive disparity compensation, the R-D performance of the proposed system can be about 2 to 4 dB higher than the current MVC coding scheme at low bitrate range.
