Fingerprint image enhancement has very important using in the preprocessing of the fingerprint image, it is directly restricting the recognition rate and speed of fingerprint recognition. Ordinary image enhancement ways can’t fill fingerprint identification system, to improve the ability of fingerprint image enhancement way, A method is presented to enhance fingerprint image and to eliminate noises effectively with optimal Gabor filters. As well as quantify the parameters of filter. Experimental results show that the algorithm can enhance the fingerprint image and make it more convenient for the minutiae extraction. The fingerprint identification algorithm and the rate of the precision can be increased efficiently.
