%X Using Gabor filter to enhance dry fingerprint image is an effective method. The key step is estimating the parameter of Gabor filter. In this paper, the direction and frequency of Gabor filter is estimated by Radon transform, and then fingerprint image is enhanced by the Gabor filter. Experiment results for some dry fingerprint images in FVC2000 fingerprint bases showed that the proposed method can produce effective enhancing with high processing rate.
