In this paper, a new orientation-based method which operates in two-step, called in Dynamic Processing (DP) system, is proposed for the determination of fingerprint reference point. For the two-step operation, it uses different orientation features at different scales: block-based orientation certainty and pixel-based segmented direction map. A block-based orientation certainty is used to describe...
Different with a traditional orientation analysis or frequency analysis which is commonly used for the fingerprint reference point determination, a new fingerprint reference point determination method based on a novel inconsistency feature obtained from the relationship between ridgelines and curves of a fingerprint is proposed. For the proposed method, an improved enhancement method is introduced...
The fingerprint quality can be used as a good predictor for fingerprint recognition performance. Knowing the fingerprint quality in advance is useful to improve the performance of fingerprint recognition system. In this paper, we propose an effective quality estimation system with 4 rules which are applied in two-step. Each rule consists of a Back-Propagation Neural Networks (BPNN) classifier based...
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...
Analyzing the quality of fingerprints in advance can be benefit for a fingerprint recognition system to improve its performance. Representative features for the quality assessment of fingerprint images from two existed types of capture devices are different. Orientation certainty level (OCL) is an effective method to extract image orientation feature. However it is not an effective estimation system...
Fingerprint identification is a technology which has been widely accepted for personal identification in many areas such as criminal investigation, access control, and Internet authentication due to its uniqueness. Most available systems for fingerprint identification use the minutiae matching for identification. The performance of minutiae extraction algorithms relies heavily on the quality of the...
