The New Focal Point Localization Algorithm for Fingerprint Registration

Abstract

The new algorithm of unique point localization for fingerprint registration is proposed. The focal point, an average center of curvature of fingerprint, is the unique and reliable reference point, suitable for fingerprint registration. In this paper, the new approach demonstrates fast and reliable reference point. Moreover, the focal point can be located even if it is out of original fingerprint boundary and singularity does not exist
