Fingerprint identification system based on DSP

As the status recognition´s mainstream way, the fingerprint recognition technology demonstrated the broad application prospect, it has used the fingerprint universality, uniqueness fully and the permanent biological features, oneself has substituted for the tradition gradually based on the symbol and the digital recognition way, at present in professions and so on network, bank, negotiable securities, medical service and insurance obtained the widespread application. Usually, the fingerprint recognition´s research mainly includes the algorithm and applies two aspects, along with the imagery processing technology´s development, each kind of related fingerprint recognition´s algorithm emerges one after another incessantly, like frequency range filter, time domain filter, directional diagram filter and so on; On the other hand, is following the digital signal processor appearance and the fast development, general DSP the chip more and more is applied in the fingerprint imagery processing.
