Efficient fingerprint minutiae extraction algorithm

Fingerprint minutiae extraction is the key to fingerprint identification technology. To overcome the deficiency of conventional fingerprint minutiae extraction algorithm, an efficient fingerprint minutiae extraction algorithm is proposed, which extracts the original minutiae points directly from the thinned image and gets the results of the preliminary feature extraction. The pseudo-feature points are removed and the true set of points is retained according to the rule of the pseudo-feature points. Experimental results show that this method can effectively eliminate all kinds of pseudo-feature points and reduce the computation time.
