HEVC帧内预测编码的快速CU决策算法
Fast CU Decision Algorithm for HEVC Intra Prediction Coding
摘要
Abstract
In this paper,a fast coding unit (CU) pruning and depth levels decision method is proposed.The early CU pruning method is performed according to a Bayes decision rule method based on the absolute sum of Hadamard transformed coefficients of the residual signal (SATD).Based on the depth information resemblance between spatio adjacent CUs and the current CU,some depths can be excluded.Experimental results show that the proposed algorithm achieves 35.9% encoder time saving on average compared to the original coding in HM10.1 with only 1.039% bit rate increment in coding performance.关键词
