An Improved Adaptive Support-Weight Method for Stereo Correspondence
Jingsong Zhao, Chen Heping · 2015
Adaptive Support-Weighted method (ASW), which sets a support weight for each pixel, based on color similarity and geometric proximity, makes an accurate disparity map. To keep the change of disparity align with edges of the reference image, we apply guided filter to smooth the cost volume generated by ASW, and use left-right consistency (LRC) to detect occlusion pixel. The experimental results demonstrate that the accuracy of disparity map has been improved.
