	Similarity of Two-Dimensional Images: An application to the forensic comparison of shoe outsole impressions Shoe outsole prints are often found in crime scenes. If a suspect is apprehended and her shoes are potential sources of the prints in the crime scene, how might a forensic scientist go about quantifying the degree of similarity between the two? This webinar is on-demand and available immdiately.
	Covering the Basic Concepts Surrounding the Weight and Strength of Evidence In this two-part presentation, we will focus on aspects of the forensic identification of source problems where the main question of interest is determining the origin of evidence with unknown source. This webinar is on-demand and available immediately.
	Research and Crime Scene Reconstruction: What should it look like? Every stake holder claims dominion over the reconstruction of a violent event (detectives, attorneys, scientists, trier-of-fact), yet most have nothing but common (non)-sense and parochial experience to guide their efforts. This webinar is on-demand and available immediately.
	Probabilistic Reporting in American Criminal Cases: A Baseline Study The reporting of forensic results is a topic of crucial importance and increasing interest. Existing scholarship primarily addresses how forensic results should or could be reported. Our purpose is to understand empirically how forensic results are actually reported in American trials today. Given that many forensic statisticians are advocating for the greater use of probabilistic reporting, this research may allow us to establish a baseline so we can measure progress toward that goal. This webinar is on-demand and available immdeiately.
	Learning Algorithms for Evaluating Forensic Glass Evidence Glass evidence may arise when a glass object is broken during the commission of a crime. Small fragments can transfer to the perpetrator. This webinar is on-demand and available immediately.
	Statistical and Computational Tools for Automated Matching of Footwear Class Characteristics We investigate the problem of automatically determining shoe outsole class characteristics from crime scene impression evidence using computer vision and machine learning techniques. This webinar is on demand and available immediately.
	Footwear Impression Evidence Examination: Overview, challenges, research and the future This presentation will provide an overview of footwear impression examination, explore directions that research in this discipline. This webinar is on-demand and available immediately.
	A panel discussion with NIST researchers and the CSAFE team on the likelihood ratio This CSAFE Center Wide Webinar was presented on March 1, 2018 by a panel of speakers who examine the impact of the likelihood ratio in a legal context, how to communicate the likelihood ratio to lay audiences and more, followed by a time for questions from the audience. This webinar is on-demand and available immediately.
	Comparing Cartridge Breechface Marks: 2D versus 3D We will describe work that we have done on an automated method to compare breechface marks on 2D images of cartridge cases, and how this transfers to 3D topographies. This webinar is on-demand and available immediately.
	Statistical Methods for Analyzing Event Time-Series Data in Digital Forensics Time-series of user-generated events are routinely captured and logged on devices such as computers and mobile phones. This webinar is on-demand and available immediately.
