Claim One:
1. A method of matching image features between a plurality of images, the method comprising the steps of: detecting a plurality of image features in a first image corresponding to a first view of a scene; detecting a plurality of image features in a second image corresponding to a second view of the scene, wherein the second image deviates from the first image as a result of camera relative motion; determining a first two-view correspondence between the plurality of detected features in the first image and the plurality of detected image features in the second image resulting in a first potential match set of candidate image features between the first and second images; and determining a second two-view correspondence, that is a refinement of the first two-view correspondence, resulting in a second potential match set of candidate image features between the first and second images, wherein the second potential match set is determined to have a maximum average strength of correspondence based at least in part on the total number of matching neighbor candidate image features for each match of the second potential match set.
