ROI-Based Fingerprint Quality Estimation

The fingerprint quality is considered as a good predictor for fingerprint recognition performance and knowing the fingerprint quality in advance is useful to improve the fingerprint recognition performance. The existing fingerprint quality estimation systems are all designed for minutiae-based fingerprint recognition system. But with the obvious advantage and widespread of ROI-based fingerprint recognition system, we proposed to design a ROI-based quality estimation system that no one has proposed before. The target of our proposed quality estimation system is the ROI instead of the whole fingerprint. And the determined ROI information is also useful for the latter recognition system. Computational complexity reduction and fingerprint matching performance improvement are shown in the experimental part.
