EVALUATION OF A SEMI-AUTOMATIC FINGERPRINT CLASSIFICATION SYSTEM WHICH CHARACTERIZES A FINGERPRINT IN TERMS OF SEVERAL IDENTIFIABLE POINTS AND MEASUREMENTS ON IT.

Abstract

THE FINGERPRINT DESCRIPTORS THAT WERE CONSIDERED PROVIDE MORE DETAILED FINGERPRINT CHARACTERIZATION INFORMATION THAN IS PROVIDED BY THE HENRY OR AMERICAN CLASSIFICATION SYSTEMS BUT NOT AS MUCH DETAIL AS IS PROVIDED BY MINUTIAE BASED FINGERPRINT ENCODING SYSTEMS. THUS, FINGERPRINT DESCRIPTORS, SUCH AS DISTANCE AND ANGLE MEASURES BETWEEN KEY POINTS ON THE FINGERPRINT MAY BE USED TO ENHANCE THE HENRY OR AMERICAN CLASSIFICATION PROCEDURES WITHOUT THE NEED FOR THE HIGHLY ADVANCED COMPUTER SYSTEMS REQUIRED BY THE PRACTICAL HIGH-SPEED MINUTIAE BASED ENCODING TECHNIQUES. THE RESULTS OF THIS STUDY INDICATED THAT THE USE OF THE DISTANCE AND ANGLE MEASURES AS FINGERPRINT DESCRIPTORS IS FEASIBLE FOR LOOP AND WHORL TYPE FINGERPRINTS. THE ENCODING OF THE DESCRIPTORS HAS BEEN SHOWN TO BE PRACTICAL FROM A TIME AND COST POINT OF VIEW. (AUTHOR ABSTRACT)
