A feasibility study on the application of MICRO XRF for latent fingermark detection on porous surfaces. [PDF]

open access: yesJ Forensic Sci
Abstract In the context of criminal investigations, latent fingermarks play a pivotal role in obtaining clues related to suspects. Presently, various physical, chemical, and optical methods are employed for latent fingermark detection. However, it is observed that when utilizing physical and chemical techniques, latent fingermarks may sometimes suffer ...

Atto-Foxes and Other Minutiae [PDF]

open access: yesBulletin of Mathematical Biology, 2021
AbstractThis paper addresses the problem of extinction in continuous models of population dynamics associated with small numbers of individuals. We begin with an extended discussion of extinction in the particular case of a stochastic logistic model, and how it relates to the corresponding continuous model.

Impact of Minutiae Errors in Latent Fingerprint Identification: Assessment and Prediction

open access: yesApplied Sciences, 2021
We study the impact of minutiae errors in the performance of latent fingerprint identification systems. We perform several experiments in which we remove ground-truth minutiae from latent fingerprints and evaluate the effects on matching score and rank-n

Characteristic and Necessary Minutiae in Fingerprints [PDF]

open access: yesJournal of the Royal Statistical Society Series C: Applied Statistics, 2022
AbstractFingerprints feature a ridge pattern with moderately varying ridge frequency (RF), following an orientation field (OF), which usually features some singularities. Additionally at some points, called minutiae, ridge lines end or fork and this point pattern is usually used for fingerprint identification and authentication.

Invariant Feature Encoding for Contact Handprints Using Delaunay Triangulated Graph

open access: yesApplied Sciences, 2023
Contact-based biometric applications primarily use prints from a finger or a palm for a single instance in different applications. For access control, there is an enrollment process using one or more templates which are compared with verification images.
