ABSTRACT:
A method of determining a movement vector between two images is disclosed. The method comprises capturing a first image using a sensor array. Next, a first feature set is extracted from the first image. A second image subsequent in time from the first image is captured. Similarly, a second feature set is extracted from the second image. The first feature set is compared to the second feature set to determine a shift in position of the second image relative to the first image. Finally, the movement vector is output based upon the shift in position.
