| Abstract(in English) | We evaluated six binarization methods and showed that the Mehtre method produces good results for fingerprint images without injury. However, preliminary experiments show that for degraded fingerprint images, the accuracy of classification is severely degraded in using binary images provided by the Mehtre method. In order to improve the Mehtre method, we propose to extract correctly the direction of the ridges and to enhance the fingerprint images. From experimental results, we see that the proposed method is effective for degraded fingerprint images. |
