Phase-correlation based fingerprint identification with rotation alignment using Fourier spectrum

Pedro Ferro FreitasRoberto de Alencar Lotufo

This paper presents a correlation-based algorithm whichuses an extension of the phase-correlation technique to determinethe angle between the fingerprint images. This extensionis based on Fourier translational and rotationalproperties. An angle validation process is proposed to improvethe angle determination. The performance of theproposed algorithm was evaluated using a database of FingerprintVerification Competition 2002 (FVC2002). Thismethod demonstrates accuracy in fingerprint reconitionand, because of its simplicity, can easily be combinedwith another methods.
