An Improvement for View Synthesis Optimization Algorithm

摘要

View synthesis optimization (VSO) allows 3D video system to improve the quality of synthesized views (SVs). Based on the latest segment-based VSO scheme, we find that not all of the intra mode and skip interval are necessary to be considered. Therefore, in this paper, an early determination of intra mode and optimal skip interval based on VSO scheme in 3D-HEVC is presented. First, we discuss a measure to select the best intra mode. Then, we decide the optimal skip interval based on statistical analysis. Experimental results indicate that the proposed algorithm achieves a reduction of 21.711% with negligible loss in rate-distortion performance compared with the original 3D-HEVC encoder, and the encoding time has also reduced to 7.869% compared with the others.
