Depth-Discrepancy-Compensated Inter-Prediction With Adaptive Segment Management for Multiview Depth Video Coding

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.
