On Matching Latent to Latent Fingerprints

Free registration required

Executive Summary

This paper presents a forensics application of matching two latent fingerprints. In crime scene settings, it is often required to match multiple latent fingerprints. Unlike matching latent with inked or live fingerprints, this research problem is very challenging and requires proper analysis and attention. The contribution of this paper is three fold: a comparative analysis of existing algorithms is presented for this application, fusion and context switching frameworks are presented to improve the identification performance, and a multi-latent fingerprint database is prepared.
