Abstract:
1. A computer-implemented method for inferring depth from a stereo image pair comprising a first image and a second image, the method comprising: generating a low resolution version of the stereo image pair; generating a low resolution disparity map corresponding to the low resolution version of the stereo image pair, the low resolution disparity map comprising a set of labels with each label in the low resolution disparity map corresponding to a pixel position in the first image and each label representing a displacement between the pixel position in the first image and a corresponding pixel position in the second image; initializing a high resolution output disparity map using initial labels determined based on the set of labels in the low resolution disparity map; refining the high resolution output disparity map to minimize an energy function; storing the high resolution output disparity map to a storage medium; and determining depth of a surface depicted in the stereo image pair using the high resolution output disparity map.
