Research on a Fingerprint Recognition Achievement System Based on TMS VC5402

介绍了自动指纹识别系统的算法原理,并说明了指纹识别系统采用TI的DSP芯片TMS320VC5402对指纹识别的预处理算法的编程实现。算法的实现采用了DSP集成开发环境(IDE)为CCS2 2。通过采用极值滤波、平滑滤波、拉普拉氏锐化、二值化、查表细化对指纹图像进行预处理,取得了良好的试验结果。达到了DSP实现指纹识别预处理的研究应用目的。

This paper introduces the theorem and algorithm of automatic fingerprint recognition system, which uses the TMS320VC5402 of TI as the core chip for its capability feature to achieve the program of fingerprint recognition. The algorithm of fingerprint recognition uses the IDE that is code composer studio22(CCS22). After preprocessing,eg exceedingly filter, smoothing, Laplacian sharpening, binalization, thinning,a good experiment result was obtained in this article. And the purpose of using DSP to process the previously processing of fingerprint recognition was achieved.
