Fast Algorithm of Fingerprint Singularity Region Enhancement

In this paper, a fast fingerprint enhancement algorithm that can improve the singularity enhancement of fingerprint is proposed. It can overcome the problem that the Gabor filter can destroy the ridge structure near the fingerprint singularity point, and the directional Fourier filter can not repair the fingerprint line effect is not obviously. The new method (FS-Gabor) can quickly repair fingerprint lines while retaining the fingerprint structure in the vicinity of the singular points. The experimental results show that the EER of the fingerprint image filtered by the FS-Gabor method is lower than the method of directional Fourier filter and Gabor.
