61. Comparing Face Recognition Algorithms to Humans on Challenging Tasks
Topic: Biometrics
Published: 10/17/2012
Authors: P Jonathon Phillips, Alice O'Toole, Xiaobo An, Joseph Dunlop, Vaidehi Natu
Abstract: We compared face identifcation by humans and machines using images taken under a variety of uncontrolled illumination conditions in both indoor and outdoor settings. Natural variations in a person's day-to-day appearance (e.g., hair style, facial e ...

62. Fingerprint Self-Captures: Usability of a fingerprint system with real-time feedback
Topic: Biometrics
Published: 9/26/2012
Authors: Yee-Yin Choong, Mary Frances Theofanos, Haiying Guan
Abstract: The performance of a biometric system depends on the quality of interaction of the biometric subject and the system. Past research has shown that fingerprint image quality is improved when the subjects received feedback from the system. However, th ...

63. BioCTS 2012: Advanced Conformance Test Architectures and Test Suites for Biometric Data Interchange Formats and Biometric Information Records
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7877
Topic: Biometrics
Published: 9/14/2012
Authors: Fernando L Podio, Dylan James Yaga, Christofer Justin McGinnis
Abstract: The Computer Security Division of NIST/ITL supports the development of biometric conformance testing methodology standards and other conformity assessment efforts through active technical participation in the development of these standards and the as ...

64. Cross-View Action Recognition via a Transferable Dictionary Pair
Topic: Biometrics
Published: 9/12/2012
Authors: P Jonathon Phillips, Jingjing Zheng, Zhuolin Jiang, Rama Chellappa
Abstract: Discriminative appearance features are effective for recognizing actions in a fixed view, but generalize poorly to changes in viewpoint. We present a method for view- invariant action recognition based on sparse representations using a transferable d ...

65. Conformance Testing Methodology for ANSI/NIST-ITL 1-2011, Data Format for the Interchange of Fingerprint, Facial & Other Biometric Information (Release 1.0)
Series: Special Publication (NIST SP)
Report Number: 500-295
Topic: Biometrics
Published: 9/5/2012
Authors: Fernando L Podio, Dylan James Yaga, Christofer Justin McGinnis
Abstract: Conformance testing measures whether an implementation faithfully implements the technical requirements defined in a standard. Conformance testing provides developers, users, and purchasers with increased levels of confidence in product quality and i ...
