Improvement Of Disparity Map Refinement Stage Using Adaptive Least Square Plane Fitting Technique

This Letter presents an improvement of disparity map refinement stage using adaptive least square plane fitting technique. This technique is proposed to increase the accuracy on the final stage of stereo matching algorithm. Fundamentally, the accuracy of matching process depends on the robustness of...
