Interoperability Study of 3D Instruments Used in Firearms Identification

June 12, 2025 / / ,
In forensic firearms identification, one of the newest emerging technologies is three-dimensional (3D) imaging. The 3D technology allows firearms examiners to virtually compare high-resolution 3D images of the surfaces of

Aligning Shoeprint Images that have nonlinear distortion effects

November 18, 2024 / / ,
Shoeprints are aligned before assessing similarity, and automatic alignment algorithms can handle differences in translation, rotation [1], and scale. But shoeprints recorded at a crime scene may be partials photographed

A Semi-Automatic Tool for Footwear Impression Alignment

June 27, 2024 / / ,
We introduce a semi-automatic alignment tool tailored for two similar footwear impressions. The term “semi-automatic” is used because the alignment process is primarily automated, yet users have the flexibility to

Quantifying Bayes Factors for Forensic Handwriting Evidence

July 12, 2023 / / ,
Questioned Document Examiners (QDEs) are tasked with analyzing handwriting evidence to make source (or writership) determinations. The Center for Statistics and Applications of Forensic Evidence (CSAFE) has previously developed computational

Quantifying Writer Variance Through Rainbow Triangle Graph Decomposition of the Common Word “the”

July 12, 2023 / / ,
Handwriting comparative analysis is based on the principle that no two individuals can produce the same writing and that an individual cannot exactly reproduce his/her handwriting. This project aims to
