Abstract
Techniques related to stereo image correspondence are discussed. Such techniques may include determining a filtered cost volume for stereo images using phase domain based costs and selecting disparity values for pixel locations based on the filtered cost volume. The filtered cost volume may be generated based on phase matching costs in single or multi-resolution.
