Abstract
A pseudo-inverse derived model-point-to-image-point transformation hypothesis generator as could be used in a computer vision system. Preferred embodiments include generation of n-point transformations directly from n point pair sets and generation of n-point transformations from sets of n point pairs defined by a preliminary three-point transformation plus sets of (n−3) points having minimal error with respect to the three-point trnasformation. Systems include salient corner extraction and hypothesis transformation verification by further sets of point pairs.
