Fingerprint image segmentation based on a combined method

Fingerprint image segmentation is part of preprocessing in fingerprint image recognition system. It has a critical effect to the fingerprint image recognition system. A combined method segmentation method is proposed in this article. We use the orientation field information combined with statistical characteristics of gray. The fingerprint image realized the second segmentation with the method proposed in this paper. The experimental results show that the method used in this paper achieves a good effect.
