METHOD, APPARATUS AND COMPUTER PROGRAM PRODUCT FOR DISPARITY MAP ESTIMATION OF STEREO IMAGES

摘要

PROBLEM TO BE SOLVED: To provide a method, apparatus and computer program product for improving disparity estimation of stereo images.SOLUTION: Receipt of first and second images is facilitated. First and second aggregated cost volumes associated with pixels of the first and second images are determined for a plurality of disparity values 710. First and second disparity maps are generated based on the first and second aggregated cost volumes 715. A confidence map corresponding to disparity values of the first image is generated based on the first aggregated cost volume. One or more infinity regions in the first image are determined based on the number of confident pixels in color segments of the first image 725. A third disparity map is generated by determining filtered disparity values for the pixels of the first image. Filtered disparity values for pixels of the one or more infinity regions are determined as prescribed disparity values 730.
