52. When High-Quality Face Images Match Poorly
Topic: Biometrics
Published: 3/9/2011
Authors: J. R. Beveridge, P Jonathon Phillips, G. H. Givens, B Draper, Mohammad Nayeem Teli, David Bolme
Abstract: In face recognition, quality is typically thought of as a property of individual images, not image pairs. The implicit assumption is that high-quality images should be easy to match to each other, while low quality images should be hard to match. Thi ...

53. Conformance Test Architecture for Biometric Data Interchange Formats - Version Beta 2.0
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7771
Topic: Biometrics
Published: 2/28/2011
Authors: Fernando L Podio, Dylan James Yaga, Mark Jerde
Abstract: The success of biometric applications is particularly dependent on the interoperability of biometric systems. Deploying these systems requires a comprehensive portfolio of biometric standards developed in support of interoperability and data interch ...

54. Measures, Uncertainties, and Significance Test in Operational ROC Analysis
Series: Journal of Research (NIST JRES)
Topic: Biometrics
Published: 1/31/2011
Authors: Jin Chu Wu, Alvin F Martin, Raghu N Kacker
Abstract: In operational ROC (receiver operating characteristic) analysis of fingerprint-image matching algorithms on large datasets, the measures and their accuracies are investigated in the three scenarios: 1) the true accept rate (TAR) of genuine scores at ...

55. Empirical Evidence for Increased False Reject Rate with Time Lapse in ICE 2006
Topic: Biometrics
Published: 1/20/2011
Authors: P Jonathon Phillips, Kevin W. Bowyer, Patrick J. Flynn, Sarah E. Baker
Abstract: We present results of the first systematic study to investigate the degree to which template aging occurs for iris biometrics. Our experiments use an image data set with approximately four years of elapsed time between the earliest and most recent ...

56. Robust Iris Recognition Baseline for the Occular Challenge
Topic: Biometrics
Published: 1/20/2011
Authors: Yooyoung Lee, Ross J Micheals, James J Filliben, P Jonathon Phillips
Abstract: Due to its distinctiveness, the human iris is a popular biometric feature used to identity a person with high accuracy. The Grand Challenge in iris recognition is to have an effective algorithm for subject verification or identification under a bro ...

57. Empirical Evidence for Iris Match Score Degradation with Time Lapse in ICE 2006
Topic: Biometrics
Published: 1/17/2011

58. Biometric Technologies and Security - International Biometric Standards Development Activities
Topic: Biometrics
Published: 1/1/2011
Author: Fernando L Podio
Abstract: Biometric technologies establish or verify the personal identity of previously enrolled individuals based on biological or behavioural characteristics. Over the past several years the marketplace for biometric-based applications has widened significa ...

59. Comparison of Confidence Intervals for Large Operational Biometric Data by Parametric and Non-parametric Methods
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7740
Topic: Biometrics
Published: 11/23/2010
Authors: Su Lan Cheng, Ross J Micheals, John Lu
Abstract: Receiver operating characteristic (ROC) or Detection Error Trade-off (DET) curves are used to measure the performance of a biometric verification or identification system. To go beyond the ROC/DET and to enhance evaluation of a verification system w ...

60. A Meta-Analysis of Face Recognition Covariates
Topic: Biometrics
Published: 11/22/2010
Authors: Yui M. Lui, David Bolme, B Draper, J. R. Beveridge, G. H. Givens, P Jonathon Phillips
Abstract: This paper presents a meta-analysis for covariates that affect performance of face recognition algorithms. Our review of the literature found six covariates for which multiple studies reported effects on face recognition performance. These are: a ...
