Fingerprint image enhancement method is based on the intrinsic characteristics of fingerprint patterns in the Fourier domain rather than spatial domain. Since, signal components of fingerprints ridges are localized in the Fourier domain. So, to enhance the localized signal components and attenuate the other noise component, fingerprint filters is designed in Fourier domain one to enhance ridge direction and other for ridge direction enhancement. Fingerprint matching is the process used to determine whether two sets of fingerprint ridge detail come from the same finger.
