Abstract
Methods and apparatuses for comparing two images to determine a set of likelihood ratios for each resolution level are described. Each location within the resolution level has its own likelihood ratio that expresses the probability that spatial features of the two images are matched, divided by the probability that spatial features of the two images are not matched. Each image may be decomposed into a multi-resolution hierarchy. A first set of likelihood ratios may be determined for each resolution level based on spatial neighborhoods of the associated locations in each of the two images within said resolution level. A second set of likelihood ratios may be determined for each resolution level by combining the first set of likelihood ratios with the final set of likelihood ratios determined at a lower resolution level, except at the lowest resolution level, where the first and second sets of likelihood ratios are the same.
