摘要
针对H.265/HEVC帧内预测模式选择算法编码耗时较长,提出一种帧内预测模式快速选择算法,通过减少参与帧内预测的模式数量,缩短编码时间。实验结果表明,在全帧内、低复杂度编码模式下,提出的算法与H.265/HEVC官方测试模型HM16.0相比,编码时间平均减少22.35%,码率(BR)增加1.623%,峰值信噪比(PSNR)降低0.081dB。
In order to reduce the encoding time cost in the H. 265/HEVC intra prediction mode selection algorithm, a fast intra prediction mode selection algorithm is proposed,by reducing the number of models to participate in intra prediction and shorten the encoding time. Experimental results show that, in full frame,low complexity of coding mode, compared with the H. 265/HEVC official test model HM16. 0, the proposed algorithm saves 22. 35% on average in time for intra-coding,and the bit rate increases 1. 623%,the PSNR decreases 0. 081dB.
