A hybrid algorithm for fingerprint enhancement

Quality enhancement of fingerprint images is important for a good performance of Automatic Fingerprint Identification System (AFIS). In this paper, a hybrid fingerprint enhancement algorithm is presented. This algorithm is based on morphological enhancement in the additive wavelet transform domain and Wave Atom denoising. The performance of the proposed algorithm has been evaluated on a set of images. The results are compared with the results obtained using morphological enhancement, only. Our proposed algorithm has given a better performance than using morphological enhancement, only.
