Abstract

A major concern in high speed, aided target recognition is getting enough information through the system, in the shortest possible time, to cover the desired targets while maintaining good target detection performance. With composite filter techniques, one can design a filter to respond over a range of scale and orientation for one target, and therefore, reduce the time required for a complete filter search. A variety of compositing techniques have been discussed on many occasions, and all have advantages and disadvantages. With available spatial light modulator technology, one must implement composite filters on devices with limited modulation states. Juday and others have proposed techniques for mapping desired filter functions onto these devices. This paper will present a filter generation methodology which combines Juday's mapping method with the MACE algorithm for generating composite filters.
