HEVC 熵编码算法优化
Optimization Algorithm of HEVC Entropy Coding
摘要
Abstract
The latest video compression standard HEVC adopts more flexible compression tools to reach a higher compression rate compared to its predecessor H .264/AVC, meanwhile the computation of HEVC is more complicated .Mainly because the larger Transform Unit and the stronger dependence between transform coefficient , entropy coding of HEVC in RDO ( Rate-Distortion Op-timization) is much more complex than that in H .264/AVC.This paper proposed several techniques to optimize the entropy cod-ing process of HEVC , including context selection optimization , significant coefficient coding optimization and different size coeffi-cient block optimization .Experiment results show that the proposed schemes can reduce on average 43% of the entropy coding time in RDO without losing compression performance .关键词
