Abstract

We present optimized biorthogonal and orthonormal wavelets for embedded zerotree wavelet compression of fingerprint images. These were obtained by simulated annealing over the wavelet filter coefficients using rms error between original and recovered images as the cost to be minimized. Linear-phase biorthogonal wavelets optimized for fingerprint image compression provide significantly improved fidelity compared either with standard wavelets or with wavelets optimized upon general images. These results are confirmed by psychovisual evaluation by two fingerprint experts whose independent rankings were in complete agreement. Filter coefficients for optimized orthonormal and linear-phase biorthogonal wavelets are tabulated
