专利名称Patent Title
一种多视点视频图像视差估计的方法
Multi view point video image parallax difference estimating method
点评:一种多视点视频图像视差估计的方法,通过Hadamard相似度系数判断当前块与其已编码的相邻块的相似性,以利用相邻块视差矢量和参考视点预测当前块的视差矢量和参考视点,并通过最佳视差矢量判定准则和快速搜索终止准则,使得目标视点图像中多数块的视差估计过程提前终止,从而降低视差估计计算复杂度,提高编码速度,与全搜索视差估计方法相比,采用本发明方法时整个编码过程的时耗仅相当于前者的1.53%~2.22%,PSNR下降不超过0.08dB,码流比特数增加不超过2.43%;与DLS快速视差估计方法相比,本发明编码过程的时耗也仅相当于DLS的11.62%~14.05%,而码流比特数略有节省,且PSNR基本相当。

Patent Title: Multi view point video image parallax difference estimating method Comment: This invention discloses a method for evaluating the viewing error of a video image of multiple viewing points, which judges the similarity of a current block and a coded adjacent block by the Hadamard similarity factor, utilizes the viewing error vector and the reference viewing points of the adjacent block to predict those of the current block to stop the period of the evaluation to most of the blocks in the target viewing point image before hand by the optimum viewing error vector decision standard and a quick search end standard to reduce the complexity of computation to the viewing error evaluation. The time loss of the entire code process in this invented method is only 1.53-2.22% of that using the total search view error evaluation method, the reduction of PSNR is not more than 0.08dB and the code stream bit is increased not over 2.43%, the time loss is only 11.62-14.05% of that of DSL.
