A Pipeline for Cartridge Case Comparisons

Conference/Workshop:
International Association for Identification (IAI) Annual Educational Conference

Type: Poster
Research Area: Firearms and Toolmarks

We introduce novel sub-procedures in the pre-processing, comparison and similarity feature steps. The sub-procedures result in an improved error rate compared to our implementation of the CMC method while also requiring fewer parameters. The fitted Decision tree model is easily interpretable.

An algorithm for forensic toolmark comparisons

Forensic toolmark analysis traditionally relies on subjective human judgment, leading to inconsistencies and lack of transparency. The multitude of variables, including angles and directions of mark generation, further complicates comparisons.…
