Abstract
Fingerprints are generally represented and analyzed in Cartesian or polar coordinates. In this paper, however, fingerprints are represented and analyzed in a novel coordinate system, called ridge coordinate system (RCS), which is based on a ridge and an oriented point on the ridge. Using RCSs based on lots of ridges, we obtain a robust representation scheme of the ridge (skeleton) image of a fingerprint. Based on this representation, an alignment-based fingerprint matching algorithm is proposed. Experimental results on FVC2002 demonstrate the validity of the proposed algorithm
