Paper Abstract

We introduce a new method for fingerprint image recognition that combines Fourier transform and wavelet transform. We use Fourier transform to produce fingerprint image spectrum, and use wavelet transform as a processor. After Fourier transform and wavelet transform, the postprocessing and fingerprint image recognition become simple and easy. We also propose a 3f multiple optical correlator with a bank of wavelet filters to implement wavelet transforms in parallel. The wavelet filters are obtained by computer generated hologram. Experimental results show that the introduced method is efficient in complicated fingerprint image recognitions.
