| Abstract: | The wavelet transformation obtains very big superiority in picture processing for the characteristic of multi-criteria analysis.In this paper,the Mexican hat wavelet is used to pretreat the fingerprint picture by joint transform correlator.The scale factor of the wavelet function has tremendous influence on fingerprint recognition result.A fast method is proposed in this paper to determine the scale factor of the wavelet function,and the computer simulation results are given. |
