Abstract
A method for finding a match between a pattern of data of relatively small size in a base of related data or relatively large size in the presence of occlusions which are gaps or noise that obscure portions, either of the pattern or of the base. The method involves masking out occluded points in both the base data and the pattern so that correlation can be computed only at those points that are not occluded.
