Fingerprint Recognition Algorithm and Its Application in the safe system
Abstract
With the rapid development of computers and networks,the accuracy of people's identity,security,and put forward higher requirements for practicality.Fingerprint recognition technology to fully use the fingerprint of the universality,uniqueness and permanent biological characteristics,has gradually replaced the traditional means of identification of password-based,currently in networking,banking,financial,medical and security Deng 行业 averaged a Guangfan application.
I studied the basic principles of fingerprint identification and the basic process.After the traditional template for fingerprint ridge filter adhesion and uneven transition in all directions,of a symmetric filter template algorithm.Improved OPTA algorithm in detail,for the burr caused by the algorithm,and more detailed bifurcation point of failure issue a detailed study,the final refinement by a relatively smooth images.Described based on structural features of fingerprint matching algorithm.Study based on fingerprint recognition safe system design,system hardware structure is given and the functions and processes of software modules.
