 Description: Aimed at the application of wavelet transform in fingerprint recognition, this paper proposes a image enhancement algorithm based on wavelet transform, using low frequency coefficient of image in the wavelet domain to estimate fingerprint ridge direction, suppress the high frequency noise on the influence of the ridge direction, experimental results show that the algorithm of ridge fuzzy fingerprint image enhancement effect is obvious. - "According to the fingerprint identification of wavelet transform in the application, and puts forward a kind of image -based on wavelet transform enhancement algorithm, using the image in low frequency coefficients of wavelet domain estimate ridge directions, restrain the fingerprint of high - frequency noise, the influence of ridge directions experiments show that this algorithm for lines blurred image enhancement effect is obvious.
