Abstract

Abstract:

Ridge orientations and ridge spatial frequencies in various regions of fingerprints represent its intrinsic characteristics.This paper proposes a new fingerprint enhancement algorithm based on wavelet transform and Gabor filtering.Then twodimensional Gabor filters is implemented by two onedimensional filters.The algorithm can improve the clarity and continuity of ridge and valley structures.The complexity is reduced.The experimental results on the fingerprints supported by FPS200 Sensor show that the proposed algorithm is fast,effective and robust.

Key words: image enhancement;wavelet transform;Gabor filter
