Abstract
The fingerprint (FP) provides an optimal foundation for Automatic Personal Identification Systems. Over the last two decades significant progress in Automatic Fingerprint Identification Systems (AFIS) has been achieved. However, the performance of AFIS still suffers from the FP image quality captured by FP sensors, the enhancement techniques for FP images and feature extraction, and the available approaches of feature matching. In this paper, we proposed a fingerprint enhancement algorithm based on Fourier filtering. In our algorithm the fingerprint enhancement were transformed from spatial domain to frequency domain by Fourier transforming. In addition, Fingerprint matching is one of the most important problems in AFIS. We proposed a minutia matching algorithm. In our algorithm, a simpler alignment method is used. We introduced ridge information into the minutia matching process in a simple but effective way and solved the problem of the matching of vector pairs with low computational cost.
