| 摘 要： | 为降低多视点视频编码中宏块模式选择带来的编码复杂度,提出了一种新的宏块模式选择快速算法.首先分析了最优模式选择的统计特征,接着根据宏块的亮度信息对图像进行区域划分,进而对不同区域选择不同的模式,以达到快速找到最优模式的目,最后提出了一种基于宏块亮度绝对均值差的宏块模式选择的快速算法.实验结果表明:提出的快速算法在保持率失真性能基本不变的情况下,编码速度比多视点视频编码校验模型JMVM提高4.14~9.83倍.

| Abstract: | To reduce the computation complexity of selecting macroblock mode in multiview video coding,a novel fast algorithm for macroblock mode selection is proposed.Firstly,analysis is conducted on the statistical features of the best mode in multiview video coding,followed by dividing the image into different areas and selecting the corresponding modes according to the characteristic of luminance in each frame.Finally,a fast marcoblock mode selection algorithm based on the mean absolute difference of macroblock lu... |
