231. Optical Path Difference Measurement Techniques for SLMs
Topic: Biometrics
Published: 3/1/2001
Authors: Patrick J Grother, D P Casasent
Abstract: A simple measurement method to obtain 2-D spatial point-by-point optical path difference (OPD) data for spatial light modulators (SLMs) is described. A simple imaging system is used that allows measurements of all SLM parameters on the same laborato ...

232. Computational and Performance Aspects of PCA-Based Face Recognition Algorithms
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6486
Topic: Biometrics
Published: 1/1/2001
Authors: H Moon, P Jonathon Phillips
Abstract: Principal component analysis (PCA) based algorithms form the basis of numerous algorithms and studies in the psychological and algorithmic face recognition literature. PCA is a statistical technique and its incorporation into a face recognition algo ...

233. Composite Filter for VanderLugt Correlator
Report Number: 6291
Topic: Biometrics
Published: 2/4/1999
Authors: Craig I Watson, Charles L. Wilson, E G. Paek, Patrick J Grother
Abstract: This paper will examines the use of composite filters for improving the effectiveness of a Vanderlugt correlator when used for fingerprint identification. A digital simulation, which accounts for noise sources in the optical setup, is used to design ...

234. Support Vector Machines Applied to Face Recognition
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6241
Topic: Biometrics
Published: 11/1/1998
Author: P Jonathon Phillips
Abstract: Face recognition is a K class problem, where K is the number of known individuals; and support vector machines (SVMs) are a binary classification method. By reformulating the face recognition problem and re-interpreting the output of the SVM classif ...

236. High Speed Temporal Characterization and Visualization of Spatial Light Modulators and Flat Panel Displays
Series: NIST Interagency/Internal Report (NISTIR)
Topic: Biometrics
Published: 1/1/1998
Authors: E G. Paek, Charles L. Wilson, John W. Roberts, Craig I Watson
Abstract: An apparatus that can characterize and visualize temporal dynamics of spatial light modulators (SLM) or flat panel displays is constructed and evaluated using a commercially available spatial light modulator as a test subject. The apparatus is base ...
