Target Tracking by Image Subtraction (La Poursuite des Cibles par la Soustraction des Images),

Abstract

Target moving against a stationary background can be enhanced and tracked by subtracting images of the scene obtained at different times. We examine by digital simulation the conditions required for such a system to give adequate tracking performance, and we give examples of the automatic tracking of an APC target in a visible-light cinefilm and of tank and APC targets in a sequence of FLIR images. We propose a possible hardware implementation of a system based on image subtraction for tracking multiple targets in real time in television-line-scan imagery. (Author)
