Developing a Repeatable and Reproducible Protocol for Establishing Combined Minutiae Frequencies
Type: Presentation Slides Research Area(s): Latent Print,Training and Education
Published: 2024 | By: Adele Quigley-McBride
Fingerprint minutia types influence LPEs’ analyses and evaluations during casework, with features perceived as rarer generally given more weight. Last year, we reported on examiner perceptions of minutia type frequency. This year, we present the next phase of our research.…
An algorithm for forensic toolmark comparisons
Type: Publication Research Area(s): Firearms and Toolmarks,Forensic Statistics
Published: 2024 | By: Maria Cuellar
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. To address this, we first generate a dataset of 3D…
Challenges in Modeling, Interpreting, and Drawing Conclusions from Images as Forensic Evidence
Type: Publication Research Area(s): Footwear,Forensic Statistics,Handwriting,Latent Print
Published: 2024 | By: Karen Kafadar
When a crime is committed, law enforcement directs crime scene experts to obtain evidence that may be pertinent to identifying the perpetrator(s). Much of this evidence comes in the form of images, either digitally transcribed (e.g.,: fingerprints, handwriting), or as…
A preliminary study of the manufacturing of breech faces
Type: Publication Research Area(s): Firearms and Toolmarks,Forensic Statistics
Published: 2024 | By: Veronica Franklin
Firearm examiners may face challenges with subclass characteristics. Subclass characteristics have the potential to be confused with individual characteristics if a careful analysis for the presence of subclass characteristics is not performed. Several case studies are reported in the literature…
