Fingerprint Identification System Based On Data Mining Research And Design

Invariance and the only fingerprints, fingerprint recognition technology has become the most extensive authentication and identification techniques. Currently, fingerprint identification technology has been widely used in public security, customs, banking, network security, and other fields. higher theoretical and practical value.In the process of Automatic Fingerprint Identification, there fingerprint image noise impact, we need to fingerprint information denoising. with the need for a large number of fingerprint matching and processing. Under such circumstances, fingerprint recognition rate is not very high, but operations are very slow. This article studies the process of fingerprint image preprocessing, gives a combination of data mining and pattern recognition technology to the fingerprint image recognition. Automatic Fingerprint Identification Technology to solve difficulties of finding practical ways.1, fingerprint image preprocessing stepusing enhanced filtering algorithm based on Gabor, The result of the enhanced effect is satisfied to us and the calculation is very low; Then, using the method of partial threshold to two value the fingerprints, further ,the dotted line having carried out thin melt on the fingerprint again , having got a set of limpid fingerprint pursues..2,the fingerprint feature extraction algorithm has been researchedIn this paper, the eight neighborhood Ridge tracking algorithm can extract fingerprint images minutiae accuratelly, Use the ridge line tracking post-processing algorithm to remove the false fingerprint minutia such as Burr, bridges and keyhole. After details of the features of this approach is adopted, could effectively eliminate counterfeit features, To improve the speed and accuracy of fingerprint matching laid a good foundation.3,the fingerprint image data mining program has been researchedData mining model in the study, based on the fingerprint image data mining system. Based on the fingerprint image data warehouse for data mining. On the basis of a fingerprint image data mining integration framework, Fingerprint Image data mining to achieve involved in the process of preparing the data, data warehouse, data mining fingerprint image, pattern recognition and neural network technology links .
