%X This paper first described the multiscale edge representation of images in the wavelet transform domain, and also discussed the representations completeness and the stability of the corresponding reconstruction algorithm. Then using the multiscale maxima representation based on the wavelet transform, we proposed for fingerprint images a non linear filtering method which was constrained by several kinds of knowledge in the scale space. The experimental results show that this filtering method has more adaptive performance and can obtain satisfactory results.
