| Abstract: | In automated fingerprint identification system, the preprocessing of fingerprint images is the key link, and the quality of fingerprint images and appropriate enhancement technique are the most crucial parts of preprocessing. The algorithm of fingerprint image enhancement based on Fourier filtering is used, fingerprint images are processed in frequency domain, and the better processing effect of fingerprint images is achieved by band-hinder filtering and orientation filtering. |
