Claim:
1. A method of selecting a homography model from point correspondences from a pair of associated images, the method comprising: partitioning at least one of the images into a plurality of partition zones; defining a predetermined exclusion zone within the plurality of partition zones; implementing a sampling constraint comprising: selecting a plurality of points in the image, each of the plurality of points being selected from a respective different one of the plurality of partitioned zones such that at least one point from each of the plurality of partitioned zones is selected; and selecting no points within the predetermined exclusion zone; and performing a sample consensus constrained by the sampling constraint to select the homography model, wherein the predetermined exclusion zone is defined before performing the sample consensus, and no points within the predetermined exclusion zone are selected to perform the sample consensus to select the homography model.
