Abstract:
1. A method of identifying combinations of matching regions in a first and second image of a common scene, the method comprising identifying first and second sets of image regions in the first and second image respectively; selecting a first and second region from the first and second set respectively; computing first and second geometrical parameters characterizing shapes of the first and second region respectively, the first and second geometrical parameters defining a first and second normalizing map that map the first and second regions to isotropic regions respectively; searching for third and fourth regions in the first and second image with matching distances to the first and second regions in spaces obtainable by mapping locations in the first and second image according to the first and second normalizing maps respectively, the search for the third and fourth regions being limited to first and/or third regions from the first and second set that lie closest to the first and second region in said spaces respectively.
