Abstract: According to the method of fingerprint image enhancement provided be fore, which is based on the direction map while omitting the global texture feat ure of fingerprint , the paper provides a method based on wavelet transform and texture filtering to enhance the fingerprint image. The experiment results indic ate the effect is good.
