stereo match 立体匹配

代码说明：

% function [dsp pixel_dsp segs labels] = total_stereo... %          (i1,i2, hs,hr,M,mins, maxs, segs, labels) % % A first take at 3D from stereo.  This function takes a stereo pair % (that should already be registered so the only difference is in the % "x" dimension), and produces a "disparity map."  The output here is % pixel disparity, which can be converted to actual distance from the % cameras if information about the camera geometry is known. %  % The output here does show which objec
