The Method Research Of Fingerprint Match And Automatic Identification

In this paper, we established an automatic fingerprint recognition software system with micro-computer.It can pretreat, do feature extraction and recognize the input fingerprint dynamically. We completed some works as below:1. We achieved some pretreatment arithmetics in common use now, they can do filtering, two-valued disposing, thining to fingerprint image. To get better disposing outcome, we ameliorated the arithmetics in the realization process.2 . In the pretreatment processing , we used some mathematics morphologic arithmetics . Using morphological thoughts to deal with fingerprint image can get preferable effect.3. Comparing the different outcomes, we educed the conclusion that which arithmetics will fit the fingerprint image better.4. Adoption layering match method to recognize fingerprint image. This method thought of the construction informations of fingerprint, it can counteract the image confusion of voices and image distortion.5. Using the first match arithmetic can improve the speed of fingerprint image recognition.
