Abstract
A method of feature matching is provided. The method includes the steps of (A) determining a set of correspondences between a set of reference feature points for a first image and a set of target feature points for a second image and (B) reducing the set of correspondences while the set of correspondences is being determined using an approximate cross-check to obtain a set of valid correspondences.
