METHOD AND APPARATUS FOR IMPROVING ESTIMATION OF DISPARITY IN A STEREO IMAGE PAIR USING A HYBRID RECURSIVE MATCHING PROCESSING

摘要

The estimation of disparity in a stereo image pair using a hybrid recursive matching processing denoted HRM with two different meander scan paths is improved. During the second meander path processing an additional disparity value calculated in the first meander path processing is used for the improved prediction of the disparity values. In a further embodiment, a third meander path processing is carried out, which third meander path corresponds to the first meander path, and the disparity values from the first meander path are used for a further improved prediction of the resulting disparity values. Instead of the third meander path processing, a bilinear filtering of disparity values can follow the second meander path processing.
