  • Abstract
    An original algorithm is presented for the high-quality enhancement of fingerprint images. Fingerprints are directionally smoothed using a position-dependent Fourier domain filter whose orientation is everywhere matched to the local ridge orientation. Thresholding then yields the enhanced image. Use of the proposed enhancement method within a working AFIS significantly improves speed and accuracy.
