Detailed Description
Block based (or fixed window) Stereo Matching class.
This class implements the baseline Block-based - aka Fixed Window - stereo matching algorithm. The algorithm includes a running box filter so that the computational complexity is independent of the size of the window ( O(1) wrt. to the size of window) The algorithm is based on the Sum of Absolute Differences (SAD) matching function Only works with grayscale (single channel) rectified images
