Abstract

One of the most frequently encountered problems in multiview depth video coding (MDVC) is the relatively low temporal and inter-view correlations when compared to that of multiview color video coding (MCVC). This directly results in degraded performance of the conventional inter-prediction. In this study, we analyze noticeable differences in statistical characteristics between MDVC and MCVC. On the basis of these differences, we propose a new depth-discrepancy compensation (DDC) method with adaptive segment management to alleviate the performance degradation. Experimental results show that the proposed method performs better than the original inter-prediction of JMVC v8.2 in terms of depth bit-savings and synthesized view quality.
