基于自适应分段跳过规则的视点合成优化方法
Optimization of viewpoint synthesis based on adaptive segment skip rule
摘要
Abstract
The performance of the standard of three dimensional high efficiency video coding ( 3 D-HEVC ) is analyzed , and aiming at its problem that the complexity of calculating synthesized view distortion change ( SVDC ) in depth coding is high , a view synthesized optimization ( VSO ) method based on adaptive segmentation skipping is pro-posed .Considering that the original method skips pixels of lines or blocks without the change of the depth data , but ignores the smaller areas that can also be skipped in VSO , the proposed method determines the region of the depth map that does not cause the synthesized view distortion according to the depth zero-distortion criterion and the tex-ture smoothing criterion .Then , the zero-distortion region is skipped based on adaptive segmentation skip before the SVDC calculation of the depth map coding .Finally, the SVDC calculation process for the area is terminated .The experimental results show that the proposed method can reduce the coding time by 14.2％while keeping the coding quality unchanged .关键词
