Abstract


The earliest , is the most widely used biometrics fingerprint recognition is used in the field of pattern recognition . This paper studies based DSK6713 development board fingerprint acquisition system , as well as fingerprint recognition algorithm . This paper first introduces the development status of the fingerprint identification system , as well as the difficulties faced by the fingerprint recognition technology and development direction , the analysis of the pros and cons of the three fingerprint technology to complete the selection of the fingerprint chip . Next semiconductor fingerprint sensor the MBF200 the basic functions in the DSK6713 development environment , based on the basic internal structure of the fingerprint sensor , designed fingerprint capture sub- board fingerprint collection . Final analysis of a conventional lack of minutiae - based fingerprint recognition algorithm , based on the basic principle of the structure of the fingerprint recognition algorithm , and its various components : the fingerprint calculation of the center point , fan , normalized , Gabor filtering, characterized extraction and comparison, in this system identification algorithm Matlab6.5 environment . Completed preliminary exploration of the fingerprint recognition system based on DSP (Digital Signal Processor) : build a fingerprint capture system based DSK6713 simulation development board and the integrated development environment CCS ( Code Composer Studio ) , Matlab6.5 environment fingerprint recognition algorithm based on structure , the establishment of a certain number of fingerprint database of fingerprints , the analysis of the comparison results , in order to verify the feasibility of the system .
