n this paper, we address the problem of matching faces across changes in pose in unconstrained videos. We pro- pose two methods based on 3D rotation and sparse representation that compensate for changes in pose. The first is Sparse Representation-based

NIST methods for calibration of surface roughness parameters and step height are described. The surface roughness parameters currently being measured include roughness average (Ra), root mean square (rms) roughness (Rq), average maximum height of the

In this paper we present results of the application of PLOT-cryoadsorption (PLOT-cryo) to the analysis of ignitable liquids in fire debris. We tested ignitable liquids, broadly divided into fuels and solvents (although the majority of the results presented
This article reviews the application of a novel rapid laser-heating technique (referred to as the laser-driven thermal reactor) for characterizing multiphase, multicomponent substances. The technique provides quantitative measurements of various relevant

Surface metrology is commonly used to characterize functional engineering surfaces. The technologies developed offer opportunities to improve forensic toolmark identification. Toolmarks are created when a tool comes into contact with a surface and causes

The PowerPlex(®) 21 System is a STR multiplex that has been optimized for casework samples while still being capable of database workflows including direct amplification. The loci included in the multiplex offer increasing overlap with core loci used in
Forensic identification of homemade explosives is critical for determining the origin of the explosive materials and precursors, and formulation procedures. Normally, the forensic examination of the pre- and post-blast physical evidence lacks specificity
Evidence Graphs model network intrusion evidence and their dependencies, which helps network forensics analyst collate and visualize dependencies. In particular, probabilistic evidence graph provide a way to link probabilities associated with different
The National Institute of Standards and Technology (NIST) has developed the NIST Ballistics Identification System (NBIS) based on three-dimensional (3D) topography measurements on correlation cells [1]. The Congruent Matching Cells (CMC) method is used for

A set of 711 samples from four U.S. population groups was analyzed using a novel mass spectrometry based method for mitochondrial DNA (mtDNA) base composition profiling. Comparison of the mass spectrometry results with Sanger sequencing derived data
Forensic Science International: Genetics, which is the official journal of the International Society for Forensic Genetics, has grown in readership and impact factor since its introduction in 2007. This article reviews some metrics of the 32 issues
A workshop on scientific publication was presented at the 2013 ISFG conference by the author, who has written four widely-used textbooks and 150 peer-reviewed articles and invited book chapters. This article is a summary of key points made during the

The consecutive matching striae (CMS) numeric criteria for firearm and toolmark identifications have been widely accepted by forensic examiners, although there have been questions concerning its observer subjectivity and limited statistical support. In
Short tandem repeats (STRs) are regions of tandemly repeated DNA segments found throughout the human genome that vary in length (through insertion, deletion, or mutation) with a core repeated DNA sequence. Forensic laboratories commonly use tetranucleotide
Desorption electro-flow focusing ionization (DEFFI), a desorption-based ambient ion source, was developed and evaluated as a possible source for field deployable ambient pressure mass spectrometry (APMS). DEFFI, based on an electro-flow focusing system

The Computer Security Division (CSD) of NIST/ITL develops conformance test architectures (CTAs) and test suites (CTSs) to support users that require conformance to selected biometric standards. Product developers as well as testing laboratories can also
The invented "NIST Ballistics Identification System (NBIS)" using three-dimensional (3D) topography measurements on correlation cells can promote high accuracy and fast ballistics identifications [1]. The use of paired correlation cells can identify the
