【Abstract】 Fingerprint matching algorithm is the core of the fingerprint algorithm,the accuracy of matching depands on the quality of the matching algorithm.For this,the fingerprint matching algorithm based on the Core points and minutiaes is given.The mathematical model of the reference point based on Core points are established with a reference fingerprint matching area on the basis of it.Fingerprint ridge line number the factor n between the reference points and minutiaes is introduced to improve the matching accuracy.And an experimental platform of fingerprint recognition algorithm is established with Visual C++6.0.Experimental results show that the algorithm has a low complexity,a higher matching accuracy,a better practicability.更多还原
