Abstract
An image processing system detects a plurality of image features in a first image corresponding to a first view of a scene, and a plurality of image features in a second image corresponding to a second view of the scene. The second image deviates from the first image as a result of camera relative motion. The system determines a two-view correspondence resulting in a potential match set having a maximum average strength of correspondence based at least in part on the total number of matching neighbor candidate image features. Additionally, a multiple-view correspondence between images results in a potential match set based at least in part on a computation of reprojection error for matched points that resulted from a projective reconstruction of the potential match set.
