一个面像识别系统的实现

用VC 这类语言实现面像识别算法，工作量很大，如果用MATLAB实现，虽然在图像处理及模式识别方面较为方便，但运行速度慢。针对这个问题给出一种开发方式，在VC 平台上开发系统主控模块及数据库系统，用MATLAB实现基于DCT变换的面像识别子系统，由MATLAB编译成C 动态库源程序，在VC 下修改并编译成动态库，由主控模块调用动态库实现面相识别。该方法具有可以灵活选择识别算法、识别率高、开发方法容易、开发周期短、可移植性强等优点。

Realization of Face Recognition System

To realize the algorithms on face recognition is hard by such program languages as VC++.Using MATLAB in image process and pattern recognition is easier, but the program will be too slow and has too much requirement for practical usage.A new method is proposed on developing face recognition programs,to develop the main system control module and database system in VC++ platform. The subsystem of face recognition based on DCT transform is realized in MATLAB, compile the MATLAB program into C++ DLL source code, then modify the code and compile it in VC++ into DLL called by the main control module. This method has the advantages of convenience to choose algorithm, high recognition rate,simple, rapid and easy to transplant.
