Abstract

This paper presents view synthesis optimization for 3D-HEVC based on a new texture smoothness process. In the original method, all pixels are exhaustively rendered to get distortions from synthesized views. Since not all pixels from the distorted depth map may cause distortions in the synthesized view, it brings unnecessary coding complexity. In this paper, lines of pixels are skipped based on the analysis of pixel regularity from smooth texture regions. It is due to the fact that the distorted disparity may not have much effect on the synthesized view in smooth texture regions. The proposed method can reduce the coding complexity of view synthesis optimization without significant performance loss.
