The problem of matching two images of the same scene is important in many applications including navigational guidance, georgraphic map matching, environmental studies and diagnosis of diseases with medical x-rays. In the general case, the images were produced by completely different sensors such as radar and optical sensors at different viewing geometries. Prior to the matching, digital signal processing must be made to line up the two images geometrically and to match their intensities. Objects of interest represented by subimages in one scene can be located in the other using hierarchical search techniques by a digital computer. Scene matching performances can then be presented in terms of the probability of a match as a function of the probability of false fix.
