METHOD AND SYSTEM FOR HYBRID RIGID REGISTRATION BASED ON JOINT CORRESPONDENCES BETWEEN SCALE-INVARIANT SALIENT REGION FEATURES

摘要

A method of aligning a pair of images includes providing a pair of images with a first image and a second image, wherein the images comprise a plurality of intensities corresponding to a domain of points in a D -dimensional space. Salient feature regions are identified (101 in both the first image and the second image, a correspondence between each pair of salient feature regions is hypothesized, wherein a first region of each pair is on the first image and a second region of each pair is on the second image, the likelihood of the hypothesized correspondence of each pair of feature regions is measured (102), and a joint correspondence is determined (103) from a set of pairs of feature regions with the greatest likelihood of correspondence.
