Abstract
As the computers and networks are rapidly developing,the accuracy of people's identity,security,and put forward higher requirements for practicality.Fingerprint recognition technology makes full use of the universal fingerprint,unique and permanent biological characteristics,has gradually replaced the traditional password-based identification methods,currently in the network,bank,financial,medical and security industries are widely 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 glitch caused by the algorithm and the bifurcation point more detailed failure issues studied in detail,the final refinement by a relatively smooth image.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
Key words:
fingerprint; direction filter; binarization; thinning; feature extraction
