The stereo matching algorithm based on the belief propaga tion (BP) has the low matching error as the global method, but has the disadvantage of a long processing time. In ad dition to a low error in the Middlebury image simulation, a new architecture based on BP shows a high-speed parallel VLSI structure of the time complexity O(N), at properly small iterations, so that it can be useful as a chip in the real-time application like the 3D video conference, the Z keying,and the virtual reality.
