Incorporating intensity edges in the recovery of occlusion regions

A method for incorporating intensity edge information into the recovery of occlusion regions using a pixel-based stereo algorithm is presented. The authors review the construction of disparity space images and their use to solve the stereo occlusion problem. The authors show the relationship between intensity edges and the disparity space images, and extend their stereo technique to use information about intensity discontinuities at occlusion edges. The combination of ground control points and edge information yields excellent occlusion regions
