Stereo matching based on color image segmentation and cross adaptive window

A method of stereo matching which is based on color image segmentation and cross adaptive window has been used to solve the problems of matching imprecision in depth discontinuity regions and low texture regions. This article first produces the matching cost based on color segmentation region by segmenting color image and the one based on cross adaptive window which makes use of color similarity, and then integrates the two to form the combined matching cost. At last it uses the fast searching method of optical parallax to narrow the matching range and then raise the efficiency rate. The result of this experiment can improve the matching accuracy in depth discontinuity regions and low texture regions and raise the matching speed.
