Abstract
A variety of implementations are described. At least one implementation modifies one or more images from a stereo-image pair in order to produce a new image pair that has a different disparity map. The new disparity map satisfies a quality condition that the disparity of the original image pair did not. In one particular implementation, a first image and a second image that form a stereo image pair are accessed. A disparity map is generated for a set of features from the first image that are matched to features in the second image. The set of features is less than all features in the first image. A quality measure is determined based on disparity values in the disparity map. The first image is modified, in response to the determined quality measure, such that disparity for the set of features in the first image is also modified.
