Abstract
In an effort to combine the advantages of optical information processing and the flexibility of digital computers, a real-time image subtraction system has been developed. A microcomputer is employed to control a Litton magnetooptic device (MOD) and also to interface the MOD to a video camera. The performance of the system in image subtraction is discussed in detail. An experimental demonstration of image subtraction is shown.Keywords
