A Novel Fingerprint Enhancement Algorithm Using Curve Mask
Fingerprint image enhancement is an essential preprocessing step in fingerprint recognition applications. In this paper, a Separable Gabor filter with Bresenham (SGB) is introduced for fast fingerprint enhancement. A Curve Mask Gabor (CMG) is designed to improve the performance of SGB. Experiments are performed on FVC2004. Results indicate that the SGB can significantly reduce computational complexity, and the CMG is also faster than traditional 2-D Gabor enhancement. Moreover, the CMG can improve the enhancement performance of SGB, and obtain better enhanced images, especially in pattern and noisy areas.
