DESCRIPTION OF THE EQUIPMENT AND METHOD OF OPERATION OF THIS SYSTEM, COMPOSED OF ELECTRO OPTICAL AND PHOTOGRAPHIC EQUIPMENT, FOR AUTOMATED SEARCH AND RECOGNITION OF LATENT FINGERPRINTS.

Abstract

THIS SYSTEM IS BASED ON THE COMPANY'S RESEARCH IN COHERENT OPTICAL PATTERN RECOGNITION AND IS INTENDED FOR SEARCHING CRIME SCENE LATENT FINGERPRINTS AGAINST POLICE AGENCY SUSPECT FILES. THE PURPOSE OF THIS SYSTEM IS TO DRAMATICALLY REDUCE THE SEARCH WORKLOAD OF LATENT EXAMINERS, AND INCREASE THE SPEED, SCOPE AND SUCCESS OF LATENT IDENTIFICATION ACTIVITIES. IT OPERATES BY MEASURING THE SIMILARITY OF FINGERPRINTS. A MICROFILMED SUSPECT FILE IS SCANNED THROUGH THE SYSTEM AND COMPARED TO THE LATENT. LIKELY MATCHES ARE DETERMINED BASED ON MACHINE MEASUREMENTS AND DECISIONS, AND THOSE CARDS ARE SEGREGATED FOR EXAMINATION AND IDENTIFICATION. THIS PAPER ALSO DESCRIBES THE RESULTS OF PERFORMANCE TESTS OF THE SYSTEM. (AUTHOR ABSTRACT MODIFIED)
