A Comprehensive Look at LatentSleuth

June 2021

LatentSleuth is a novel software tool set designed for (and with direct feedback from) latent print examiners. The toolset includes a small-scale automated fingerprint identification system (AFIS) matcher that leverages a novel matching algorithm that calculates a warp between a latent print image and a given reference print image. This webinar will demonstrate a comprehensive quantification of a latent images entire structure and how that quantification is exploited in a commercially available workstation for latent print examination. 

Lessons Learned from Proficiency Test Results in Bloodstain Pattern Analysis

April 2021

This webinar will evaluate the submitted responses for bloodstain pattern analysis proficiency tests over the past several years with the purpose of gaining insight into trends within the science.  The focus will be on erroneous conclusions and how an evaluation of the most problematic patterns can assist in moving the discipline forward.

This webinar was presented by the NIJ Forensic Technology Center of Excellence on April 15, 2021.
