Claim One:
1. A method for determining a disparity search range for a current stereo image of a scene based on a set of stereo images of the scene, comprising steps of: selecting a subset of stereo images from the set of stereo images, the subset includes the current stereo image and at least one neighboring stereo image, wherein the neighboring stereo image is temporally-neighboring to the current stereo image; determining a disparity histogram for each stereo image in the subset of stereo images to form a set of disparity histograms; determining, for each pair of disparity histograms in the subset of disparity histograms, a weighting factor representing a similarity between histograms in the pair of the disparity histograms to produce a set of weighting factors; determining a weighted disparity histogram as a weighted sum of the disparity histograms in the set of disparity histograms based on the set of the weighting factors and the set of disparity histograms; and determining the disparity search range from the weighted disparity histogram, wherein the steps are performed by a processor.
