ABSTRACT:
A system for detecting an object in a scene. The invention (10) includes memory (12) for storing a first frame of image data represented by a plurality of input signals I.sub.o. A spatial filter (16) is included for spatially filtering a second frame of image data represented by a plurality of input signals I.sub.o to provide first spatial filter output signals of the form .eta..sub.s I.sub.o. These signals are subtracted from the first frame of image data to provide difference signals of the form .eta..sub.D I.sub.o, where .eta..sub.D represents a measure of object registration. A second spatial filter (18) is included for spatially filtering the difference signals to provide spatially filtered difference signals of the form .eta..sub.s .eta..sub.D I.sub.o. Finally, the signals are processed (30) to extract the measure of object registration .eta..sub.D.
