Title: Composite Filter for VanderLugt Correlator
Published: February 04, 1999
Abstract: This paper will examines the use of composite filters for improving the effectiveness of a Vanderlugt correlator when used for fingerprint identification. A digital simulation, which accounts for noise sources in the optical setup, is used to design and test composite matched spatial filters. Results are presented for a real time video image database containing 10 seconds of video from 200 fingers. Using the composite matched spatial filter, the Vanderlugt correlator is getting 70% correct indentifications with no false positives.
