The method processes a global optimal motion estimation in overlapped window region, and use the hierarchical structure to overcome the disadvantages of fixed size block matching, so have a correct disparity vector, and produce a smoother disparity map. 由于该方法在交叠窗口区域进行全局最优估计,并且采用多分辨率的结构克服固定块匹配的缺陷,得到较准确的视差矢量,并且产生光滑的视差图。
Based on overlapped smooth window characteristic of complex lapped transform, the method could decrease the discontinuity of block edge, and thus produce a smooth motion field, which may reduce bit stream for motion vector. 利用复数交叠变换的交叠窗口平滑特性,该方法有效减少块边缘不连续性,因此得到的光流场较为平滑,从而减少运动矢量的传输码流。
