Intra-Frame Coding of Depth Maps to Restrain Coding Error Pervasion

Yang Xu;Li Bing-bing;Ma Xiang;Chang Yi-lin;State Key Laboratory of Integrated Services Networks,Xidian University;  
In order to improve the coding quality of depth maps and the virtual synthesis quality of 3D videos,an intra-frame coding method to restrain the coding error pervasion is proposed. In this method,the depth map is firstly segmented into a flat region and an edge region according to the features of depth maps. Then,the distortion pervasion properties in the two regions are analyzed,based on which the blocks or sub-blocks that cause the distortion pervasion are corrected by using a correction value during the rate-distortion optimization of macro blocks. Thus,a large number of following blocks or sub-blocks influenced by the distortion pervasion may possess a smaller value of rate-distortion cost function. Experimental results indicate that,as compared with the intra-coding method presented by JMVC 8. 5 and the intra-frame predication method based on segmentation,the proposed coding method improves the average peak signal-to-noise ratio of the virtual synthesis view by 0. 30 and 0. 25 dB,respectively.
