Abstract
A method of aligning a first image with a second image, the method includes approximately locating the second image; scaling the first image to the approximate size of the second image; positioning the scaled first image over the approximate location of the second image; generating a measure of fit between the first image and the second image; re-positioning the second image and repeating the above steps to obtain an increased measure of fit value. A method of synchronizing a first sequence of images with a second sequence of images includes creating a first index pointer identifying an image in the first sequence of images; creating a second index pointer identifying an image in the second sequence of images; comparing the image identified by the first index pointer with the image identified by the second index pointer; incrementing the first index pointer to identify the subsequent image in the first sequence of images; and repeating the above steps until the image identified by the first index pointer matches the image identified by the second index pointer.
