Researches Of Fingerprint Synergetic Identification System Based On TMS320C54x

With the development of electronic computer and information technology, the Identification technology using biometric have drawn more attention. Fingerprint-based identification technology as a very important method used biometric features, is always the hotspot.Classic automatic systems for fingerprint comparison are based on minutiae matching. They almost involve time-consuming fingerprint image's pretreatment, which is very complicated algorithm implementations and need advanced hardware, so it is difficult to popularize. Synergetics identification method, as a rising subject, has rapid and robust capability on image identification. In this paper, fingerprint orientation field, which is a globe feature of fingerprint, has been adopted to identify fingerprint combining Synergetics identification method.The main work in this paper as follows: The evolutionary development and application background of Identification technology using biometric feature have been described, especially of Fingerprint-based identification. The information about fingerprint-based identification has been collected. Research of fingerprint image's pretreatment that is key part of classic fingerprint-based identification has been done, and the performance of some algorithm has been compared; The approaches of pattern recognition using Synergetics have been summarized. Making use of image processing and synergetic identifying technique, I have worked on two different fingerprint-based identification modes, namely verification" and "identification". The approach of two modes has been proposed and implemented with C++ program language in this paper. For emulating the actual condition, the samples of different individual's fingerprintshave been taken to make experiment with the approach in practicability and in good time subsequently. In addition, the algorithm was simulated on Code Composer Studio IDE, which provides a development platform that enables Tl customers to evaluate and develop applications for the DSP. The result of the simulation showed that the algorithms meet with the requirement of TMS320C54x, and it was possible to integrated into DSP practicably for popularizing.
