Pattern Evidence Research in CSAFE-An Update

CSAFE is a NIST Center of Excellence in Forensic Science. A large portion of CSAFE’s research portfolio is on what is known as pattern evidence, which encompasses any evidence that can be represented as an image. Examples of pattern evidence include footwear prints, firearms and toolmark striations, fingerprints, blood spatter and handwriting. In today’s webinar we provide an update of research projects that focus on all of those examples, and propose interesting directions for future research.
