How Minutiae Frequency is Perceived and Used by Fingerprint Analysts in the Evaluation of Fingerprint Evidence

July 17, 2023 / Presentation Slides / Latent Print

Analysts consider the appearance, placement, and number of features within a fingerprint pattern (called minutiae) that correspond when deciding whether two fingerprints originated from the same person. Little is known

Analyzing spatial responses: A comparison of IRT- based approaches

July 12, 2023 / Publication / Forensic Statistics, Latent Print

We investigate two approaches for analyzing spatial coordinate responses using models inspired by Item Response Theory (IRT). In the first, we use a two-stage approach to first construct a pseudoresponse
