Abstract
An efficient method of matching a segment in one image with a segment in another image. Fourier transforms are implemented to aid in the process. In one embodiment, a method involves identifying a displacement of a segment present in a first image and a second image, the displacement representing a relative change in position of the segment between the first and second images.
