51. Video-based Face Recognition via Joint Sparse Representation
Topic: Biometrics
Published: 4/26/2013
Authors: P Jonathon Phillips, Yi-Chen Chen, Vishal M Patel, Sumit Shekar, Rama Chellappa
Abstract: In video-based face recognition, a key challenge is in exploiting the extra information available in a video; e.g., face, body, and motion identity cues. In addition, different video sequences of the same subject may contain variations in resolution, ...

52. VASIR: An Open-Source Research Platform for Advanced Iris Recognition Technologies
Series: Journal of Research (NIST JRES)
Report Number: 118.011
Topic: Biometrics
Published: 4/22/2013
Authors: Yooyoung Lee, Ross J Micheals, James J Filliben, P Jonathon Phillips
Abstract: The performance of iris recognition systems is frequently affected by input image quality, which in turn is vulnerable to less-than-optimal conditions due to illuminations, environments, and subject characteristics (e.g., distance, movement, face ...

53. Camera Recognition
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7921
Topic: Biometrics
Published: 3/26/2013
Authors: Michelle Potts Steves, Brian C Stanton, Mary Frances Theofanos, Dana E. Chisnell, Hannah Wald
Abstract: The Department of Homeland Security‰s (DHS) United States Visitor and Immigrant Status Indicator Technology (US-VISIT) program is a biometrically-enhanced identification system primarily situated at border points of entry such as airports and sea ...

54. Sensitivity Analysis for Biometric Systems: A Methodology Based on Orthogonal Experiment Designs
Topic: Biometrics
Published: 3/4/2013
Authors: Yooyoung Lee, James J Filliben, Ross J Micheals, P Jonathon Phillips
Abstract: The purpose of this paper is to introduce an effective and structured methodology for carrying out a biometric system sensitivity analysis. The goal of sensitivity analysis is to provide the researcher/developer with the insight and understanding of ...

55. Examination of Downsampling Strategies for Converting 1000 ppi Fingerprint Imagery to 500 ppi
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7839
Topic: Biometrics
Published: 1/22/2013
Authors: Shahram Orandi, John M Libert, John Donald Grantham, Lepley Margaret, Bruce Bandini, Kenneth Ko, Lindsay M. Petersen, Stephen S Wood, Stephen G. Harvey
Abstract: Currently the bulk of fingerprint data in operational is captured, processed and stored at 500 ppi using the WSQ compressed digital format. With the transition to 1000 ppi, some systems will unavoidably contain an overlap between 500 ppi and 1000 ppi ...

56. Video-based Face Recognition via Joint Sparse Representation
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7906
Topic: Biometrics
Published: 1/2/2013
Authors: P Jonathon Phillips, Vishal M Patel, Yi-Chen Chen, Rama Chellappa
Abstract: In video-based face recognition, a key challenge is in exploiting the extra information available in a video. In addition, different video sequences of the same subject may contain variations in resolution, illumination, pose, and facial expressions. ...

58. Dictionary-based Face Recognition from Video
Topic: Biometrics
Published: 12/10/2012
Authors: P Jonathon Phillips, Yi-Chen Chen, Vishal M Patel, Rama Chellappa
Abstract: The main challenge in recognizing faces in video is effec- tively exploiting the multiple frames of a face and the accompanying dynamic signature. One prominent method is based on extracting joint appearance and behavioral features. A second method ...
