Abstract
The present invention is a system and a method for processing stereo images utilizing a real time, robust, and accurate stereo matching system and method based on a coarse-to-fine architecture. At each image pyramid level, non-centered windows for matching and adaptive upsampling of coarse-level disparities are performed to generate estimated disparity maps using the ACTF approach. In order to minimize propagation of disparity errors from coarser to finer levels, the present invention performs an iterative optimization, at each level, that minimizes a cost function to generate smooth disparity maps with crisp occlusion boundaries.
