| Abstract: | Some algorithms for fingerprint- classification based on preprocessed images are discussed. A method of reference point orientation dispensed with iteration is proposed, which has the advantages of simplicity, high speed and precision. Then, based on the method of feature extraction with half region of directional field, the issue of fingerprint multi-classification is solved with BTA-SVM. The experiment results show that the new algorithm can achieve a high rate of classification. |
