In order to improve the promptness,reliability and convenience of the ID system,the authors of this paper have designed a face recognition system through DSP,in which the skin-based face detection algorithm and the face recognition algorithm based on the principal component analysis of the wavelet transform are the software algorithms.The hardware platform of the system is composed of a DSP microprocessor (DM642),CCD camera sensors and displays.The testing results show that the designed face recognition system has the advantages of high recognition speed and success rate.%为了提高身份识别系统的实时性、可靠性和便捷性,设计了基于DSP的人脸识别系统.基于肤色的人脸检测算法和基于小波变换的主成分分析的人脸识别算法构成了所设计系统的软件算法;DSP(DM642)微处理器、CCD传感器摄像头和显示屏等构成了该系统的硬件平台.测试结果表明,设计的人脸识别系统具有识别速度快和成功率高等优点.
