Abstract

The primary application considered in this paper is target detection in infra-red (IR) imagery for ground surveillance application. The problem is characterized by the need to rapidly search large areas, and ascertain the presence and location of threat objects. The challenge is in not only processing large images rapidly, but also reducing false alarm rates while achieving high levels of correct target detections. Performance is a function of many factors including the clutter type and density, the quality of the image and target signature, and the adequacy of the target data base. Although many types of target detection algorithms exist, we use a method based on quadratic correlation filters. The results of independent tests and evaluations by Night Vision Laboratory are also presented.
