Fingerprint matching using discreet wavelet packet transform

In this work the discrete wavelet packet transform (DWPT) based feature extraction method is illustrated for fingerprint matching. The wavelet packet transform is applied on small area of fingerprint image. The performance of wavelet packet decomposition is evaluated on the standard database available at the Website of Bologna University. The redundancy of discrete wavelet packet transform is reduced without compromising the accuracy. The discrete wavelet packet transform with reduced redundancy gives the better performance over the discrete wavelet transform (DWT), Gabor filter and minutiae based method.
