基于DSP的人脸识别系统设计

介绍了以DSP为核心的实时人脸识别系统设计。通过对视频制式组成的充分学习，设计了包括图像采集编码、CPLD控制存储器存取切换系统，以及图像编码输出在内的硬件平台。在软件设计过程中，分别设计了自动采集样本程序、主分量分析（PCA）提取特征程序、包含K近邻分类（KNN）及判否的程序3部分。系统采用了浮点DSPTMS320C6713作为中央处理单元，实时性好，识别精度高，可脱机运行，携带方便，可推广到运动检测、动态跟踪等领域。

Implementation of the Face Recognition System Based on DSP

In this paper,a face recognition system based on DSP is introduced.With sufficient knowledge of video standards,the hardware is designed including the image sampling and coding system,alternative accessing system which is controlled by CPLD,and video displaying system.In designing the software,programs are divided into three parts,namely the automatically extracting face samples,PCA feature extracting and KNN classifier.With the use of the float DSP TMS320C6713,the system has the advantages of good real-tim...
