Abstract:
1. A method of synchronizing a first sequence of images with a second sequence of images, the method comprising aligning the sequences spatially by performing, on one or more sample frames method comprising: (i) identifying the location of the second image within a window; (ii) scaling the first image to the approximate size of the second image; (iii) positioning the scaled first image in the window in a position approximately corresponding to the location of the second image in its window; (iv) generating a measure of fit between the first image and the second image; (v) re-positioning one of the images and repeating steps (iv) and (v) to identify positions having an increased measure of fit value; and then synchronizing the sequences by: (a) creating a first index pointer identifying an image in the first sequence of images; (b) creating a second index pointer identifying an image in the second sequence of images; (c) comparing the image identified by the first index pointer with the image identified by the second index pointer; (d) incrementing the first index pointer to identify the subsequent image in the first sequence of images; and (e) repeating steps (c) and (d) until the image identified by the first index pointer matches the image identified by the second index pointer.
