Abstract
The present work reports a three stage matching algorithm for latent fingerprints. The algorithm includes preprocessing by a transform domain filter, computation of moments as invariant features and finally, use of a nearest neighbor clustering analysis for fingerprint matching. The transform domain filter involves selective amplification of the spectral band containing the highest energy, and subsequent use of a band-pass filter. The enhanced image is almost noise-free, and shows prominent features in the fingerprint that cannot be extracted by other conventional enhancement techniques. The moments of enhanced fingerprints provide invariant features. The classification of fingerprints is performed by a nearest neighbor clustering of the moment features characterizing a specific fingerprint.
