Dr.S.Arumuga Perumal, T.C. Rajakumar, Dr.N.Krishnan . Fuzzy based Filtering Approach on Histogram Specification for Fingerprint Image Enhancement. International Journal of Computer Applications. 23, 8 ( June 2011), 30-33. DOI=10.5120/2905-3815
Fingerprint identification is the most important area in biometric identification. The quality of the fingerprint image is an important one for a reliable matching process. The contrast of the image can be enhanced at the preprocessing stage of fingerprint matching. Contrast is the difference between two neighboring pixels. In this paper we describe a fuzzy modeling approach which may be used for reducing the noise and increaseing the brightness of the ridges. Fuzzy filter values are analyzed and better results are produced in the image domain. The probabilities of gray values are determined from the position of the input image pixel. The result indicates the good performance of the proposed fuzzy histogram.
