An Evaluation of Automated Latent Fingerprint Identification Technology (Phase II)

April 2, 2009
Author(s)
Michael D. Indovina, Vladimir N. Dvornychenko, Elham Tabassi, George W. Quinn, Patrick J. Grother, Stephen Meagher, Michael D. Garris
The National Institute of Standards and Technology (NIST), with the cooperation of eight technology providers, performed a test of accuracy for searching latent fingerprints when using automatically extracted features and matching (AFEM). This test is

NIST Special Database 19. NIST Handprinted Forms and Characters Database

October 16, 2008
Author(s)
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
