The Challenge of Face Recognition From Digital Point-and-Shoot Cameras

June 25, 2013
Author(s)
P J. Phillips, J. R. Beveridge, David Bolme, Bruce A. Draper, Geof H. Givens, Yui M. Lui, Hao Zhang, W T. Scruggs, Kevin W. Bowyer, Patrick J. Flynn, Su L. Cheng
Face recognition is appearing in personal and commercial products at an astonishing rate, yet reliable face recognition remains challenging. Users expect a lot; they want to snap pictures and have their friends, family and acquaintances recognized. This

A New Metric for Latent Fingerprint Image Preprocessing

June 23, 2013
Author(s)
Mary Frances Theofanos, Andrew Dienstfrey, Brian Stanton, Haiying Guan
Although fingerprint recognition is a well-studied area, forensic fingerprint preprocessing based on computational theory is still a relatively new domain in need of further scientific study and development of standards of best practice. Latent fingerprint

Evaluation of dome-input geometry for pyroelectric detectors

June 24, 2013
Author(s)
Jinan Zeng, Leonard M. Hanssen, George P. Eppeldauer
Dome-input pyroelectric radiometers with different black coatings were developed to extend the spectral responsivity scale from near infrared (NIR) to 20 μm. The reflective dome with shiny gold-coating has been known to be an efficient light trap to

Harnessing 3D Scattered Optical Fields for sub-20 nm Defect Detection

June 24, 2013
Author(s)
Bryan M. Barnes, Martin Y. Sohn, Francois R. Goasmat, Hui Zhou, Richard M. Silver, Abraham Arceo
Experimental imaging at =193 nm of sub-resolved defects performed at several focus positions yields a volume of spatial and intensity data. Defects are located in a differential volume, given a reference, with up to 5x increase in sensitivity.

OBSERVATIONS ON THE GENERATION OF TOXIC PRODUCTS IN THE ISO/TS 19700 CONTROLLED EQUIVALENCE RATIO TUBE FURNACE AND THE CONTROLLED ATMOSPHERE CONE CALORIMETER

June 24, 2013
Author(s)
Nathan D. Marsh, Richard G. Gann, John R. Shields, Marc R. Nyden
Efforts are underway in several research groups to adapt existing flammability test methods for the determination of yields of toxic compounds such as CO, HCN, and HCl. These include the NFPA 269 / ASTM E 1678 radiant furnace apparatus, the ISO/TS 19700

Quantifying Network Topology Robustness Under Budget Constraints

June 24, 2013
Author(s)
Assane Gueye, Aron Lazska
To design robust network topologies that resist strategic attacks, one must first be able to quantify robustness. In a recent line of research, the theory of network blocking games has been used to derive robustness metrics for topologies. A network

Four Measures of Nonlinearity

June 23, 2013
Author(s)
Joan Boyar, Magnus Find, Rene Peralta
Cryptographic applications, such as hashing, block ciphers and stream ciphers, make use of functions which are simple by some criteria (such as circuit implementations), yet hard to invert almost everywhere. A necessary condition for the latter property is
