Side Information Fusion Algorithm Based on Reliability Evaluation in DMDVC

XIONG Wenshi;QING Linbo;WU Xiaohong;CHEN Zhenzhen;College of Electronic Information Engineering, Sichuan University;  
In depth-based multi-view distributed video coding(DMDVC), the quality of side information is one of the key factors that affect the compression efficiency. In order to make full use of the temporal side information, spatial side information and depth map to improve the quality of side information of the DMDVC system, a fusion algorithm based on reliability evaluation is proposed. The motion compensated temporal interpolation(MCTI) is used to generate temporal side information, and then the spatial side information can be generated using the depth image based rendering(DIBR) technique. The object's fast movement in the scene would affect the quality of temporal side information and the use of DIBR to generate spatial domain side information would lead to holes. To solve these problems, this paper selectively corrects the fast moving regions in temporal side information or the holes and edge regions in spatial side information. The experimental results show that the algorithm can effectively fuse the temporal side information and the spatial side information, which can achieve up to 5.6 d B improvement over [4].
