Comparing Cartridge Breechface Marks: 2D versus 3D
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.

Explaining Source Conclusions to a Lay Audience
Explaining Source Conclusions to a Lay Audience

Forensic scientists are often asked to evaluate whether two items have (or might have) a common source. What is the best way for them to explain the strength of their conclusions in reports and testimony?

Thinking About Likelihood Ratios for Pattern Evidence
Thinking About Likelihood Ratios for Pattern Evidence

The likelihood ratio has been proposed as a logical way to summarize forensic evidence. In pattern evidence disciplines; however, the application of likelihood ratios is challenging because of the high-dimensional data involved and the lack of relevant probability models (among other issues).
