Abstract
Fingerprint enhancement is a key issue in fingerprint minutiae extraction due to various image qualities. Most of exist fingerprint enhancement algorithms need to estimate the ridge orient and ridge distance, which are used to design the enhancement filter. However ridge distance estimation is a rather dffIcult task due to the fingerprint image quality and singularity, therefbre, the ridge distance estimate usually fails in those case and leads to enhancement algorithm failed. In this paper, we propose an AM-FM basedfingerprint image enhancement algorithm, which uses a novel Dominate Component Analysis (DGA,) technique to estimate the dominate component, and uses band pass filter to enhance those component rather than directly estimate the ridge distance, ridge orientation. Experiment results show that our enhancement algorithm leads to signflcant image quality improvement as well as the system efficient.
