collimation error

, greedy disparity estimation procedure consists sequentially of three steps: segmentation-based disparity calibration, narrow occlusion handling and multi-directional weighted least square fitting.

接着,为了更好地消除弱纹理区域、重复纹理区域和宽遮挡区域等复杂歧义性,视差后处理中采用贪婪估计方案,包括基于分割的视差校准、窄遮挡处理及多方向自适应加权最小二乘拟合填充。
