摘 要: 高效、快速的视差匹配是立体视频处理中的一项关键技术。本文在分析立体图象序列的视差矢量与运动矢 量之间的相关性的基础上,提出一种基于MPEG-2的立体视频编码中的视差匹配快速算法。实验结果表明,与全搜 索法相比,在保证重建图象质量的前提下,快速算法能显著降低视差估计的计算复杂度。 Fast and efficient disparity correspondence of stereo video coding based on MPEG-2 is a key technology in stereo video processing. On the basis of analyzing the correlation between disparity vector and motion vector, a fast disparity correspondence estimation algorithm for stereo video coding, based on MPEG-2, was presented. The experimental results show that, compared with the full search algorithm, the fast algorithm can greatly reduce disparity estimation complexity while the reconstructed image quality is close to the one by means of full search method.
