چکیده

At the NIST March 2010 workshop on “The Future of NFIQ”, the development of a new (open source) version of NFIQ in consultation and collaboration with users and industry was recommended. Following this recommendation, NIST and BSI set up a joint project for the development of a successor version of NFIQ. This paper explains the reasons and needs for the development and details the planned approach and development process.

Towards Improving the NIST Fingerprint Image Quality (NFIQ) Algorithm

The NIST Fingerprint Image Quality (NFIQ) algorithm has become a standard method to assess fingerprint image quality. However, in many applications a more accurate and reliable assessment is desirable. In this publication, we report on our efforts to optimize the NFIQ algorithm by a retraining of the underlying neural network based on a large fingerprint image database. Although we only achieve...

Nist F Ingerprint Image Quality (nfiq) Compliance Test

In August 2004 NIST published a novel measure of fingerprint image quality, which is designed to predict performance of minutia-based fingerprint matching systems. The definition and methodology of NIST Fingerprint Image Quality (NFIQ) is documented in [1] and its implementation is publicly available; but subject to US export control laws as part of NIST Fingerprint Image Software 2 (NFIS2) dis...

An Analysis of Altered Fingerprint Detection, Recognition and Verification

The common positioning of Automated Fingerprint Identification Systems (AFIS) in law enforcement and border control submissions has sensitive the need for safeguarding that these systems are not compromised. Whereas numerous problems associated to fingerprint system safekeeping have been considered, including the use of phony fingerprints for masquerading personality, the problem of fingerprint...

Impact of Image Quality on Performance: Comparison of Young and Elderly Fingerprints

Performance of fingerprint recognition systems is heavily influenced by the quality of fingerprints provided by the user. Image quality analysis is traditionally performed using local and global structures of fingerprint images like ridge flow, analysis of ridge-valley structures, contrast ratios etc. With large scale deployment of fingerprint recognition in systems like US VISIT program, image...

Fingerprint Quality Assessment Combining Blind Image Quality, Texture and Minutiae Features

Biometric sample quality assessment approaches are generally designed in terms of utility property due to the potential difference between human perception of quality and the biometric quality requirements for a recognition system. This study proposes a utility based quality assessment method of fingerprints by considering several complementary aspects: 1) Image quality assessment without any r...
