快速HEVC帧间预测编码单元深度选择算法
Fast Coding Unit Depth Selection Algorithm for Inter-frame Prediction of HEVC
摘要
Abstract
In order to improve the encoding efficiency,this paper proposes a fast CU (Codizy Unit) depth selection algorithm.First,the MPD (Mean Prediction Depth) of current CU is calculated and then the current CU is classified based on MPD so as to reduce the redundant traversal.Secondly,the CU depth of current CU is judged further for stop based on the ratio of the RD (Rate Distortion) cost of the collocated CUcol (Co-located CU) with the reference frame to the total sum of depth.Experimental result shows that the proposed method decreases the average encoding time by 59％ under the condition of decreasing bit rate by 0.10％ and decreasing PSNR by 0.08 dB,while compared with the reference algorithm in this paper,the encoding time is reduced by 11％ on average,and decreases the encoding complexity and improves the encoding efficiency.关键词
