摘要 立体视频编码中的关键问题之一就是视差估值 .文中利用分层复数交叠变换域相位相关方法进行匹配提出了一种新的视差估值方法 .理论分析和仿真试验证明 ,本文中的方法克服了传统方法的缺点 ,提高了视差场的平滑度 。 One important problem in the stereo sequence is disparity estimation. We propose a new method for disparity estimation in this paper, in which the hierarchical complex lapped transform phase correlation is used. The results show that this method can overcome the shortcoming of traditional method, improve the smoothness of the disparity map, reduces the computation complexity of disparity estimation.
