ABSTRACT:
A system and method of tracking moving targets in video images comprises retrieving a reference video frames each comprising arrays of digital pixels; computing a first averaged image for each of the reference video frames, wherein each pixel value of the first averaged image comprises an average pixel intensity value associated with all corresponding pixel values in the reference video frames; computing a second averaged image for a second set of the reference video frames, wherein each pixel value of the second averaged image comprises an average pixel intensity value associated with all corresponding pixel values in the reference video frames; viewing an input video frame comprising arrays of digital pixels; subtracting the input video frame from the first and second averaged images separately to form at two difference images; and combining the difference images to form a change map.
