IREX I: Performance of Iris Recognition Algorithms on Standard Images

October 30, 2009
Author(s)
Patrick J. Grother, Elham Tabassi, George W. Quinn, Wayne J. Salamon
The IREX program supports the development of interoperable iris imagery for use in high performance biometric applications. The IREX evaluation, was conducted in cooperation with the iris recognition industry to demonstrate that standardized image formats

Biometric Standards

August 27, 2009
Author(s)
Patrick J. Grother
This chapter is intended as an introduction to biometric standards, and as a survey of the major efforts in the field. Published consensus standards in a wide range of fields have existed for many years. Biometric standards, however, have been developed

Patrick J. Grother
Special Database 19 contains NIST's entire corpus of training materials for handprinted document and character recognition. It publishes Handprinted Sample Forms from 3600 writers, 810,000 character images isolated from their forms, ground truth

NIST Special Database 20. NIST Scientific and Technical Document Database

October 16, 2008
Author(s)
Patrick J. Grother
The images in this database contain a very rich set of graphic elements such as graphs, tables, equations, two column text, maps, pictures, footnotes, annotations, and arrays of such elements. No ground truthing or original typesetting information is

MINEX II Performance of Fingerprint Match-on-Card Algorithms - Phase II Report

February 29, 2008
Author(s)
Patrick J. Grother, Wayne J. Salamon, Michael D. Indovina, Craig I. Watson
The MINEX II trial was conducted to evaluate the accuracy and speed of Match-on-Card verification algorithms. These run on ISO/IEC 7816 smart cards. They compare conformant reference and verification instances of the ISO/IEC 19794-2 COMPACT CARD

Concepts of Operations (CONOPS) for the Evaluation of Latent Fingerprint Technologies (ELFT)

June 12, 2007
Author(s)
Vladimir N. Dvornychenko, Brian J. Cochran, Patrick J. Grother, Michael D. Indovina, Craig I. Watson
The National Institute of Standards and Technology (NIST) is conducting a series of tests for evaluating the state of the art in Automated Latent Fingerprint matching. The intent of the testing is to quantify the core algorithmic capability of contemporary

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

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
