Abstract

Fingerprint image enhancement is a preprocessing step in fingerprint recognition applications. In this paper, an improved algorithm for enhancement of fingerprint image is proposed. The proposed method includes additional adaptive filtering and segmentation steps to the previous fingerprint image enhancement methods based on Gabor filter. The adaptive filtering step enhances the edges of the fingerprints. The segmentation step combines four techniques to separate the fingerprint image from the background. The results show an improvement on the fingerprint for visual inspection and for automatic feature extraction for recognition
