The National Institute of Standards and Technology (NIST) Evaluation of Latent Fingerprint Technologies Extended Feature Sets (ELFT EFS) consists of multiple ongoing latent algorithm evaluations. This report describes the design, process, results, and conclusions of ELFT EFS Evaluation number 1; an accuracy test of latent fingerprint searches using features marked by experienced human latent fingerprint examiners, in addition to automatic feature extraction and matching (AFEM).
