摘要
为了在保证PSNR和bitrate的基础上,提高立体视频编码的速度,首先,对立体视频序列各模式进行统计分析,然后进行快速帧间模式选择算法的比对,并最终确定使用基于图像细节程度的快速帧间模式选择算法进行编码。实验结果表明,在图像质量和压缩效率基本不变的情况下,大幅度提高了H.264立体视频编码的速度。
This paper aimed to increase multi-view video encoding speed on guaranteed PSNR and bitrate. First,the paper made a statistic analysis of each mode of multi-view video sequences. Then,made a comparison of fast inter mode decision algorithm to come to a conclusion that fast inter mode decision algorithm based on the intrinsic complexity of the macroblock should be used for encoding. The experimental results indicate that this algorithm highly increases the H. 264 multi-view video encoding speed on premise of almost invariant image quality and compression efficiency.
