Abstract

In an automatic fingerprint identification system, image enhancement step and match component can benefit from the estimation of fingerprint image quality. In this paper, a criterion for fingerprint image quality is established based on the gradient of fingerprint image. We test the quality measuring method using the proposed criterion on the fingerprint image database, DB3 in FVC2002. From the experimental results , it can be shown that the method is available for estimating the fingerprint image quality.
