| Abstract: | Smooth filter can restrain or eliminate noise; high quality images can be got. An integrative system of fingerprint recognition was built up, and fingerprint recognition was carried out through preprocessing, characteristic extraction, classification and recognition. Methods of filters enhancement during preprocessing were studied, and the processing effect of neighbouring area average, Gauss flatness and median filter were intercompared. Fingerprint recognition experiments were carried out, and Least Square Support Vector Machine was adopted during recognition. The results were intercompared. |
| Keywords: | smooth filter characteristic extraction Least Square Support Vector Machine fingerprint recognition |
