一种改进的HEVC帧内预测算法
An Optimized Algorithm for HEVC Intra Prediction
摘要
Abstract
In order to solve the problem of the high complexity of CU division in HEVC intra prediction,an optimized intra prediction algorithm of HEVC is proposed.Based on the time relativity of the video sequence,the algorithm can compares the depth of CU of the current coding unit with the adjacent CUs as well as the same position CU of the previous frame,skips unnecessary block prediction and sub block prediction.This process can accelerate encoding time.The experimental results show that the algorithm provides averagely 30％ reduction of intra coding time compared with the one accepted by HM10.0 with drops of 0.04dB PSNR and increase of 1％ BiteRate,which can ensure the encoding quality and reduce the encoding time.关键词
