Fingerprint Image Quality Parameters: A Review

Abstract

Biometrics system has now become the most popular method for the person
identification. The quality of the biometric image captured should be robust enough to
minimize/eliminate duplicate and fake identities. The Integrated Automated Fingerprint
Identification System (IAFIS) Appendix F Standard and PIV Specification Standards are
acclaimed standards for validating the quality of biometric images. To assure the good quality of
biometric image it is important that the fingerprint scanner shall be capable of producing images
that exhibit good geometric fidelity, sharpness, detail rendition, gray-level uniformity, and grayscale dynamic range, with low noise characteristics. In this paper the biometrics type, fingerprint
scanner image quality specification according to the ISO (the International Organization for
Standardization) and IEC (the International Electrotechnical Commission) standards is given.
These specifications provide criteria for ensuring the image quality of fingerprint scanners that
input fingerprint images to, or generate fingerprint images from within, an Automated Fingerprint
Identification System (AFIS).
