| Abstract: | In this paper,we analysed relevant methods for the preprocessing and feature extraction for fingerprint. In the course of the research. two kinds of methods. space directional filtered method and equalizationenhancement method. for noise elimination. a new thinning method which can only pass over a source fingerprint image is presented. and the definition of the center of a fingerprint is improved. |
