Class for computing stereo correspondence using the block matching algorithm

Class for computing stereo correspondence using the block matching algorithm, introduced and contributed to OpenCV by K. Konolige.

Usage

bm = cv.StereoBM('NumDisparities',0, ...);
bm.MinDisparity = ...;
disparity = bm.compute(left, right);
