Abstract

As the fingerprint enhancement algorithm in the existing image segmentation is not complete and cannot repair the broken crack line fingerprint problem well

we take the fractal theory as the foundation

use differential box counting algorithm and the Gabor filter enhancement

through the computation fingerprint image’s field of directions and the frequency field

and has designed a kind of fingerprint image intensification algorithm.The experimental result indicated that this algorithm raised the fingerprint i...
