【 摘 要 】

Prospective 3D video transmission systems that would use compression of both multiview video and depth maps was dealt with in this paper. To get the optimal synthesized view quality with the transmission bit rate being constant, it firstly analyzed the overall behavior of combined coding and view synthesis, color and depth data with different coding qualities were combined for intermediate view synthesis. Then, individual coding results for color and depth data were evaluated in order to investigate, how well the synthesized view quality was at certain compression. Finally, a new joint coding method for multi-view video plus depth (MVD) was proposed by utilizing the optimal combinations of the quantization parameters of color videos and the corresponding depth maps. Simulation results demonstrated that the proposed method decreased the bit-rate by 12.72%~24.02% in comparison with JMVC and can be used to guide sequence-level texture/depth coding for 3D video compression. The proposed method has better performance in optimizing the tradeoff between bit-rate and visual quality.
