Abstract
A computer-implemented method for detecting landmark pairs in a pair of images is provided. The method includes receiving a pair of images, sampling the pair of images to generate reduced-resolution pairs of images, identifying features in the reduced-resolution pairs of images, matching the features in the image pairs, using the matched features in an increased resolution pair of images as guides for feature matching, and through iteratively guiding feature matching, identifying landmarks in the full-resolution pair of images.
