Abstract

ELFT-EFS Evaluation 1 is an evaluation of the accuracy of latent matching using features marked by experienced human latent fingerprint examiners. The purpose of this test is to evaluate the current state of the art in latent feature-based matching, by comparing the accuracy of searches using images alone with searches using different feature sets. The features sets will include the current IAFIS latent feature set, and different subsets of the Extended Feature Set (EFS) features proposed by CDEFFS . A key result of the test is to determine when human feature markup is effective. Because human markup is expensive in terms of time, effort, and expertise, there is a need to know when image-only searching is adequate, and when the additional effort of marking minutiae and extended features is appropriate.
