Face Recognition Based on Frontal Views Generated from Non-Frontal Images

October 1, 2005
Author(s)
V Blanz, Patrick Grother, P. Jonathon Phillips, T Vetter
This paper presents a method for face recognition across large changes in viewpoint. Our method is based on a Morphable Model of 3D faces that represents face-specific information extracted from a dataset of 3D scans. For non-frontal face recognition in 2D

Overview of the Face Recognition Grand Challenge

October 1, 2005
Author(s)
P J. Phillips, P J. Flynn, W T. Scruggs, K W. Bowyer, J S. Chang, K Hoffman, J Marques, J Min, W Worek
Over the last couple of years, face recognition researchers have been developing new techniques, such as recognition from three-dimensional and high resolution imagery. These developments are being fueled by advances in computer vision techniques, computer

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

Linear and Generalized Linear Models for Analyzing Face Recognition Performance

August 17, 2005
Author(s)
J. R. Beveridge, Geof H. Givens, Bruce A. Draper, P. Jonathon Phillips
This paper introduces linear models (LM), generalized linear models (GLM), and generalized linear mixed models (GLMM) for analyzing performance of face recognition algorithms. These three statistical techniques are applied to analyzing the affect of

Two Finger Matching with Vendor SDK Matchers

July 1, 2005
Author(s)
Craig I. Watson, Charles L. Wilson, Michael D. Indovina, Brian J. Cochran
This report is an extension of the NIST Studies of one-to-one Fingerprint Matching with Vendor SDK Matchers which evaluated the accuracy of SDK (Software Development Kit) based on COTS (Commercial Off-The-Shelf) fingerprint matching systems for one-to-one

Nonparametric Analysis of Fingerprint Data

May 2, 2005
Author(s)
Jin Chu Wu, Charles L. Wilson
This paper demonstrates that, for large-scale tests, the match and non-match similarity scores have no specific underlying distribution function. The forms of these distribution functions require a nonparametric approach for the analysis of the fingerprint

Slap Fingerprint Segmentation Evaluation 2004 Analysis Report

March 1, 2005
Author(s)
Brad Ulery, R. A. Hicklin, Craig I. Watson, Michael D. Indovina, Kayee Hanaoka
The Slap Fingerprint Segmentation Evaluation 2004 (Slap Seg04) was conducted to assess the accuracy of algorithms used to segment slap fingerprint images into individual fingerprint images. Segmenters from ten different organizations were evaluated on data

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

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

NIST Biometric Evaluations and Developments

February 1, 2005
Author(s)
Michael D. Garris, Charles L. Wilson
This paper presents an R&D framework used by the National Institute of Standards and Technology (NIST) for biometric technology testing and evaluation. The focus of this paper is on fingerprint-based verification and identification. Since 9-11 the NIST

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

Common Biometric Exchange File Format (CBEFF), Augmented

April 15, 2004

Fernando L. Podio, J S. Dunn, L Reinert, C J. Tilton, L O'Gorman, P Collier, Mark Jerde, B Wirtz
This report is an augmentation of the original standard, which was published as NISTIR 6529 (January 2001). Common Biometric Exchange File Format (CBEFF) describes a set of data elements necessary to support biometric technologies in a common way. These

Fingerprint Image Quality

April 13, 2004

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
