Effect of Image Size and Compression on One-to-One Fingerprint Matching

February 1, 2005
Author(s)
Craig I. Watson, Charles L. Wilson
NIST has conducted testing of one-to-one fingerprint matching systems to evaluate the effect of image size and compression on the accuracy of the one-to-one matching process. Images from three live-scan fingerprint scanners collected by the Departments of

Matching Performance for the US-Visit IDENT System Using Flat Fingerprints

November 29, 2004
Author(s)
Charles L. Wilson, Michael D. Garris, Craig I. Watson
This report discusses the flat to flat matching performance of the US-VISIT fingerprint matching system. Both one-to-many matching used to detect duplicate visa enrollments and one-to-one matching used to verify the identity of the visa holder are

Fingerprint Vendor Technology Evaluation 2003: Summary of Results and Analysis Report

June 30, 2004
Author(s)
Charles L. Wilson, Patrick J. Grother, Ross J. Micheals, S C. Otto, Craig I. Watson, R. A. Hicklin, H Korves, Brad Ulery, M Zoepfl
The Fingerprint Vendor Technology Evaluation (FpVTE) 2003 was conducted to evaluate the accuracy of fingerprint matching, identification, and verification systems. The FpVTE is one of the tests that NIST has conducted in order to fulfill part of its

Studies of One-to-One Fingerprint Matching With Vendor SDK Matchers

June 24, 2004
Author(s)
Craig I. Watson, Charles L. Wilson, Karen Marshall, Michael D. Indovina, Robert D. Snelick
NIST has conducted testing of one-to-one SDK (Software Development Kit) based COTS fingerprint matching systems to evaluate the accuracy of one-to-one matching used in the US-VISIT program. Fingerprint matching systems from eight vendors not used in US

Studies of Biometric Fusion Executive Summary

April 19, 2004
Author(s)
Craig I. Watson, Brad Ulery, R. A. Hicklin, William Fellner, P Halinan
This is an evaluation of different score-level fusion techniques, and the results of a variety of fusion experiments using face and fingerprint data from 187,000 individuals, with matcher scores from three fingerprint and three face recognition systems

Fingerprint Image Quality

April 13, 2004
Author(s)
Elham Tabassi, Charles Wilson, Craig I. Watson
In this report, we propose a new definition of quality of fingerprint impressions and present detailed algorithms to measure image quality for fingerprints. We define fingerprint image quality as a predictor of matcher performance before a matcher

Studies of Fingerprint Matching Using the NIST Verification Test Bed (VTB)

July 1, 2003
Author(s)
Charles L. Wilson, Craig I. Watson, Michael D. Garris, R. A. Hicklin
A series of fingerprint matching studies have been conducted on an experimental laboratory system called the Verification Test Bed (VTB). The VTB is a collection of commercial off the shelf (COTS) computer hardware, an open-source operating system, and a

Fingerprint Matching Using Distortion Tolerant Filters

February 13, 2003
Author(s)
Craig I. Watson, D P. Casasent
The purpose of this paper is to discuss the use of distortion tolerant filters to improve the performance of fingerprint correlation matching. Previous work has shown that correlation matching of fingerprints is susceptible to larger false alarm rates than

User's Guide to NIST Fingerprint Image Software (NFIS)

November 1, 2001
Author(s)
Michael D. Garris, Craig I. Watson, R. McCabe, Charles L. Wilson
This report documents a public domain fingerprint image software distribution developed by the National Institute of Standards and Technology (NIST) for the Federal Bureau of Investigation (FBI). The software technology contained in this distribution is a

Distortion-Tolerant Filter for Elastic-Distorted Fingerprint Matching

March 1, 2000
Author(s)
Craig I. Watson, Patrick J. Grother, D P. Casasent
This paper gives results for using distortion tolerant filters to improve performance of fingerprint correlation matching. Three types of distortion tolerant filters were tested: summation, weighted, and MINACE. A set of 55 fingers were used from NIST

Performance of Electrically Addressed Spatial Light Modulators

March 3, 1999
Author(s)
Patrick Grother, M L. Hsieh, Craig I. Watson
We address two important performance limitations of commonly available spatial light modulations. First we present a method for the determination of modulation transfer function and amplitude modulation from CCD captures of imaged gratings. Second, we
