Optimized wavelets for fingerprint compression


We present opt imized b iorthogonal 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… (More)
