61. WSQ Problem with Two-Thumb Captures from Large Platen Live-Scan Devices
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7746
Topic: Biometrics
Published: 11/18/2010
Author: Craig I Watson
Abstract: This paper investigates an issue with the Wavelet Scalar Quantization (WSQ) compression algorithm which causes severe degradation of the compressed image. The problem was first noticed when compressing the two-thumb images from live-scan identificati ...

62. SlapSegII Analysis: Matching Segmented Fingerprint Images
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7747
Topic: Biometrics
Published: 11/16/2010
Author: Craig I Watson
Abstract: This report is an extension of the SlapSegII evaluation and will study the affect of slap fingerprint segmentation on matching accuracy. This study will compare matching accuracy of hand marked segmentation data with the automated segmentation algori ...

63. Recognizing people from dynamic and static faces and bodies: Dissecting identity with a fusion approach
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7721
Topic: Biometrics
Published: 9/13/2010
Authors: Alice J. O'Toole, P Jonathon Phillips, Samuel Weimer, Dana A. Roark, Julianne Ayadd, Robert Barwick, Joseph Dunlop
Abstract: The goal of this study was to evaluate human accuracy at identifying people from static and dynamic presentations of faces and bodies. Participants matched identity in pairs of videos depicting people in motion (walking or conversing) and in \best" s ...

65. Image specific error rate: A biometric performance metric
Topic: Biometrics
Published: 8/20/2010
Author: Elham Tabassi
Abstract: Image-specific false match and false non-match error rates are defined by inheriting concepts from the biometric zoo. These metrics support failure mode analyses by allowing association of a covariate (e.g., dilation for iris recogniti ...

68. An Empirical Study of Korean Cultural Effects on the Usability of Biometric Symbols
Topic: Biometrics
Published: 6/17/2010
Authors: Young-Bin Kwon, Yooyoung Lee, Yee-Yin Choong
Abstract: Biometrics is an umbrella term for methods that identify an individual based on physiological and/or behavioral characteristics such as fingerprint, face, iris, retina, vein, palm, voice, gait, signature, etc. The use of biometric systems is increasi ...

69. Report on the Evaluation of 2D Still-Image Face Recognition Algorithms
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7709
Topic: Biometrics
Published: 6/17/2010
Authors: Patrick J Grother, George W Quinn, P Jonathon Phillips
Abstract: The paper evaluates state-of-the-art face identification and verification algorithms, by applying them to corpora of face images the population of which extends into the millions. Performance is stated in terms of core accuracy and speed metrics, an ...

70. Quantifying How Lighting and Focus Affect Face Recognition Performance
Topic: Biometrics
Published: 6/13/2010
Authors: J. R. Beveridge, David Bolme, B Draper, G. H. Givens, Yui M. Lui, P Jonathon Phillips
Abstract: Recent studies show that face recognition in uncontrolled images remains a challenging problem, although the reasons why are less clear. Changes in illumination are one possible explanation, although algorithms developed since the advent of the P ...
