Joint Video-depth Predictive Coding for 3D. Television Systems
Scene geometry can be represented by depth images,which need to be transmitted to 3DTV terminals to assist in rendering of virtual view at an arbitrary view-point. Efficient compression is needed to reduce the expenditure for transmitting depth images. Similarity of motion information between video and depth images is analyzed,and a joint video-depth predictive coding scheme is proposed to reuse the motion information obtained in video coding to assist depth coding. The coding scheme comprises two parts,video-depth motion information copy and video-depth motion information prediction. Experimental results show that the proposed coding scheme can utilize the motion information of encoded video efficiently,and improve the coding efficiency of depth images significantly.
