HEVC是ITU-T和ISO联合制定的新一代视频编码标准。由于采用了许多新的技术,HEVC的编码效率是H.264标;住的大约2倍,但是编码的复杂度也随之增加。,提出了一种针对HEVC帧内预测模式选择的快速算法,该方法综合了基于视频内容分析的方法和基于统计信息的方法并加以优化。实验结果表明,在比特率和PSNR几乎不变的情况下,编码时间平均可以减少30%。
HEVC is the latest video coding standard proposed by JCT-VC. Since a lot of new techniques are adopted, the coding efficiency is about twice than previous standard H. 264. However, the encoding complexity is also increasing. In this paper, a fast algorithm for intra prediction mode is proposed to reduce the encoding time. The proposed method utilizes both video content analysis method and statistical analysis. Experimental results show that the encoding time is reduced by 30% with nearly the same bitrate and PSNR.
