Abstract:
1. One or more computer-readable random access memory devices comprising computer-executable instructions for occlusion handling in stereo imaging, the computer-executable instructions comprising instructions for: segmenting a first stereo image to result in a coarse segmentation, the first stereo image being either a left or right image; labeling the coarse segmentation of the first stereo image; setting an initial estimate of a disparity and occlusions between the first stereo image and a second stereo image, the initial estimate based on the labeling of the coarse segmentation, the second stereo image being the other of the left or the right image; segmenting the first and second stereo images to result in fine segmentations, the fine segmentations being more granular than the coarse segmentation; optimizing energy within an alpha-expansion move, the alpha expansion move initially based on the fine segmentations and the initial estimate, and thereafter based on a current solution indicated by disparities and occlusions of the fine segmentations; pairing two fine segmentations, the pairing performed by: obtaining disparities and occlusions of pixels in the matched pair of segmentations within the stereo images based on the energy optimization.
