一种HEVC帧内编码的快速算法
Fast intra coding algorithm for HEVC
摘要
Abstract
To solve the problem of high computational complexity and long coding time of intra prediction in High Effi-ciency Video Coding(HEVC), a fast intra coding algorithm is proposed. Firstly, the spatio-temporal correlation of adja-cent Largest Coding Unit(LCU)depth is used to narrow the depth range of LCU and then unnecessary depth can be split or prune early. At the same time, according to whether Planar is selected as the optimal prediction mode, the number of prediction modes is reduced in different methods. Compared with original HM10.0, experimental results show that the proposed algorithm can save nearly 30%encoding time with the same coding performance and has practical applications.关键词
