31. Effects of JPEG 2000 Lossy Image Compression on 1000 ppi Latent Fingerprint Casework
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7780
Topic: Biometrics
Published: 10/25/2013
Authors: Shahram Orandi, John M Libert, John Donald Grantham, Frederick R Byers, Lindsay M. Petersen, Michael D Garris
Abstract: This paper presents the findings of a study conducted to measure the impact of JPEG 2000 lossy compression on the comparison of 1000 ppi latent fingerprint imagery and 1000 ppi exemplar fingerprint imagery. Combinations of image pairs that vary ...

33. On the Existence of Face Quality Measures
Topic: Biometrics
Published: 9/30/2013
Authors: P Jonathon Phillips, J. Ross Beveridge, David Bolme, Bruce A. Draper, Geof H. Givens, Yui M. Lui, Su Lan Cheng, Mohammad Nayeem Teli, Hao Zhang
Abstract: We address the problem of the existence of quality measures for face recognition. We introduce the concept of an oracle quality measure, which is an optimal quality measure. We approximate oracle quality measures by greedy pruned ordering (GPO). ...

34. Propagation of Facial Identities in a Social Network
Topic: Biometrics
Published: 9/30/2013
Authors: P Jonathon Phillips, Tao Wu, Rama Chellappa
Abstract: We address the problem of automated face recognition on a social network using a loopy belief propagation frame- work. The proposed approach propagates the identities of faces in photos across social graphs. We characterize performance in terms of st ...

35. SNoW: Understanding the Causes of Strong, Neutral, and Weak Face Impostor Pairs
Topic: Biometrics
Published: 9/27/2013
Authors: P Jonathon Phillips, Amanda Sgroi, Patrick J. Flynn, Kevin W. Bowyer
Abstract: The Strong, Neutral, or Weak Face Impostor Pairs problem was generated to explore the causes and impact of impostor face pairs that span varying strengths of nonmatch. We develop three partitions within the impostor distribution of a given algorithm. ...

36. Estimating the Number of Manually Segmented Cellular Objects Required to Evaluate the Accuracy of a Segmentation Algorithm
Topic: Biometrics
Published: 9/22/2013
Authors: Adele P Peskin, Joe Chalfoun, John T Elliott, Karen Kafadar
Abstract: We propose a new strategy for estimating the number of cellular objects that should be manually segmented for evaluating the segmentation accuracy of an algorithm. The strategy uses geometric and edge quality measurements that are directly related to ...

37. Conformance Test Architecture and Test Suite for ANSI/NIST-ITL 1-2011 NIEM XML Encoded Transactions
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7957
Topic: Biometrics
Published: 9/18/2013
Authors: Fernando L Podio, Dylan James Yaga, Christofer J. McGinnis
Abstract: The latest version of the ANSI/NIST-ITL standard was published in November 2011 (AN-2011). In addition to specifying Record Types in traditional encoding, the standard includes the specification of National Information Exchange Model (NIEM) Extensibl ...

38. Effects of Decomposition Levels and Quality Layers with JPEG 2000 Compression of 1000 ppi Fingerprint Images
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7939
Topic: Biometrics
Published: 8/27/2013
Authors: John M Libert, Shahram Orandi, Michael D Garris, John D. Grantham
Abstract: As part of NIST‰s investigative efforts to support development of the FBI Next Generation Identification (NGI) systems, this investigation evaluates effects on image fidelity of wavelet transform decomposition and quality layer options for JPEG 2 ...

39. Biometric Face Recognition: From Classical Statistics to Future Challenges
Topic: Biometrics
Published: 8/13/2013
Authors: P Jonathon Phillips, Geof H. Givens, J. Ross Beveridge, Bruce A. Draper, David Bolme, Yui M. Lui
Abstract: Automated face recognition has moved from science fiction to reality during the last twenty years. For high quality frontal face images, recognition errors have been cut in half every two years as more sophisticated algorithms are developed ...

40. The National Institute of Standards and Technology: NIST Contributions to Biometrics Technology
Topic: Biometrics
Published: 8/1/2013
Author: Bradford J Wing
Abstract: NIST has been at the forefront of information technology in its application to biometrics for almost 50 years. Early work revolved around developing hardware and software to perform automated analysis of fingerprint images and development of voice ...
