| Abstract: | The fingerprint is regarded as a kind of biological characteristic of human beings. It has the advantages of uniqueness stability, being able to gather, never being able to be from the subject, etc. It has already become the effective means that the personal identity has discerned. In this paper, the wavelet transform is introduced, and then based on wavelet decomposition and reconstruction, the fingerprint image compressing,getting rid of noise and extracting features are fulfilled. Experimental results have verified that this method is effective in preprocessing fingerprint images. |
