基于增强层残差编码的分布式可分级 H EVC压缩研究
Research on enhancement layer residual encoding based distributed scalable HEVC compression
摘要
Abstract
Aimed at the problem of high coding complexity of scalable video compression method,this paper proposed a en-hancement layer residual encoding based distributed scalable HEVC compression method.Firstly,it utilized the same SI crea-ting method by both of encoder and decoder to obtain the highest compression rate,and used several SI frames to estimate the correlation between EL residual and SI residual.Then,it used the correlation model to decide the count of the least significant bit(LSB)and generated the syndrome,the decoder reconstructed the enhancement layer information based on this syndrome. Lastly,it designed adaptive coding mode selection mechanism to select the coding mode with better RD-rate performance. Comparison experiment results show that the proposal encoding complexity and RD performance outperform the relevant methods.关键词
