About

NIST is conducting a series of tests for evaluating the state of the art in latent fingerprint matching. The intent of this testing is to quantify the core algorithmic capability of contemporary matchers with the goal of providing automated assistance to latent examiners. Testing will be conducted using fully automated software-only implementations in a "lights out" environment, however, a subset of searches will be conducted with human markup of the input latent images to help identify algorithmic limitations. Initially testing will include only single-finger latent searches. Multi-finger latent searches may be investigated in subsequent tests.

The initial test (Phase I) has been completed and aggregate results are available here. Phase I was a proof of concept which demonstrated automated feature extraction from latent images, and the ability to match those features against enrolled 10-print backgrounds and produce candidate lists of manageable size.

Phase II testing commences December of 2007 and expands on Phase I through the use of improved software and larger datasets to give refined estimates of capability. Performance will be explored at both 500 and 1000 ppi, with and without supplementary Regions-of-Interest (ROI) markup. Phase II is limited to those participating in Phase I,

Current Status

ELFT07 Phase I testing is complete and Phase II has been announced.

NEW [November 13, 2007]
