Abstract
A method of registering first and second images includes the steps of (a) accepting each of the first and second images, (b) contrast enhancing each of the first and second images to form enhanced first and second images, (c) sampling each of the enhanced first and second images to form sampled first and second images, (d) computing a correlation between the sampled first and second images, (e) computing a first coarse common area for the sampled first image and a second coarse common area for the sampled second image, (f) defining corresponding corner patches for each first and second coarse common area, (g) computing a correlation between each corresponding corner patch, and (h) defining a complex interpolating polynomial function based upon the correlation of step (g).
