Performance of Biometric Quality Measures

April 16, 2007
Author(s)
Patrick Grother, Elham Tabassi
We document methods for the quantitative evaluation of systems that produce a scalar summary of a biometric sample¿s quality. We predicate this on the idea that the quality measure predicts performance, whether by design or correlation. We do this

When to Fuse Two Biometrics?

June 13, 2006
Author(s)
Elham Tabassi, Patrick J. Grother, George W. Quinn
Biometric fusion, acquisition and combination of multiple pieces of evidence of identity, can achieve higher accuracy of biometric recognition than using a single biometric. However, fusion increases the cost or throughput of the system since it requires

MINEX Performance and Interoperability of the INCITS 378 Fingerprint Template

March 2, 2006
Author(s)
Patrick Grother, R. McCabe, Craig I. Watson, Michael D. Indovina, Wayne J. Salamon, Patricia A. Flanagan, Elham Tabassi, Elaine M. Newton, Charles L. Wilson
While the interchange of fingerprint image data provides the greatest interoperability between dissimilar fingerprint recognition systems, standards exist that specify the location and formatting of processed minutiae locations data, or templates. Minutiae

A Novel Approach to Fingerprint Image Quality

September 14, 2005
Author(s)
Elham Tabassi, Charles L. Wilson
We present a novel measure of fingerprint image quality, which can be used to estimate fingerprint match performance. This means presenting the matcher with good quality fingerprint images will result in high matcher performance, and vice versa, the

NFIQ Compliance Test

February 14, 2005
Author(s)
Elham Tabassi
In August 2004 NIST published a novel measure of fingerprint image quality, which can be used to estimate fingerprint match performance. The definition and methodology of NIST Fingerprint Image Quality (NFIQ) is documented in [1] and its implementation is

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

Face Recognition Vendor Test 2002: Evaluation Report

March 1, 2003
Author(s)
P J. Phillips, Patrick J. Grother, Ross J. Micheals, D M. Blackburn, Elham Tabassi, M Bone
The Face Recognition Vendor Test (FRVT) 2002 is an independently administered technology evaluation of mature face recognition systems. FRVT 2002 provides performance measures for assessing the capability of face recognition systems to meet requirement for
