Abstract

This paper presents an efficient depth map coding method based on color information in multi-view plus depth (MVD) system. As compared to the conventional depth map coding in which depth video is separately coded, the proposed scheme involves color information for depth map coding. In details, the proposed algorithm subsamples input depth data along temporal direction to reduce the bit-rate, and non-encoded depth frames are recovered at the decoder side guided by the motion information extracted from the decoded color video. The simulation results shows the high coding efficiency of the proposed scheme, and it also shows that recovered depth frame are not much different from the reconstructed one. Furthermore, it can even provide temporally consistent depth map which results in better subjective quality for view-interpolation.
