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

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

Face Recognition Vendor Test 2002 Supplemental Report

February 1, 2004
Author(s)
Patrick J. Grother
Further analyses of the systems tested in the Face Recognition Vendor Test 2002 are reported. These supplement those covered in the primary Evaluation Report of March 2003. Specifically this report is intended to appeal to a more specialized audience; it

Human Identification from Body Shape

October 1, 2003
Author(s)
Afzal A. Godil, Patrick J. Grother, Sanford P. Ressler
In this paper, we investigate the utility of static anthropometric distances as a biometric for human identification. The 3D landmark data from the CAESAR database is used to form a simple biometric consisting of distances between fixed rigidly connected

The NIST Human ID Evaluation Framework

April 1, 2003
Author(s)
Ross J. Micheals, Patrick J. Grother, P J. Phillips
In this paper, we investigate the utility of static anthropometric distances as a biometric for human identification. The 3D landmark data from the CAESAR database is used to form a simple biometric consisting of distances between fixed rigidly connected

Face Recognition Vendor Test 2002 Performance Metrics

March 1, 2003
Author(s)
Patrick Grother, Ross J. Micheals, P. Jonathon Phillips
We present the methodology and recognition performance characteristics used in the Face Recognition Vendor Test 2002. We refine the notion of a biometric imposter, and show that the traditional measures of identification and verification performance are

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

Dependence Characteristics of Face Recognition Algorithms

January 1, 2002
Author(s)
Andrew L. Rukhin, Patrick J. Grother, P J. Phillips, Stefan D. Leigh, E M. Newton, Nathanael A. Heckert
Nonparametric statistics for quantifying dependence between the output rankings of face recognition algorithms are described. Analysis of the archived results of a large face recognition study shows that even the better algorithms exhibit significantly

Transformation, Ranking, and Clustering for Face Recognition Algorithm Performance

January 1, 2002
Author(s)
Stefan D. Leigh, Nathanael A. Heckert, Andrew L. Rukhin, P J. Phillips, Patrick J. Grother, E M. Newton, M Moody, K Kniskern, S Heath
The performance of face recognition algorithms is recently of increased interest, although to date empirical analyses of algorithms have been limited to rank-based scores such a cumulative match score and receiver operating characteristic. This paper

Optical Path Difference Measurement Techniques for SLMs

March 1, 2001
Author(s)
Patrick J. Grother, D P. Casasent
A simple measurement method to obtain 2-D spatial point-by-point optical path difference (OPD) data for spatial light modulators (SLMs) is described. A simple imaging system is used that allows measurements of all SLM parameters on the same laboratory

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
