本文的目的是提供一个我开发的SSE优化的，C++库，用于人脸检测，你可以马上把它用于你的视频监控系统中。涉及的技术有：小波分析，尺度缩减模型（PCA,LDA,ICA），人工神经网络（ANN），支持向量机（SVM），SSE编程，图像处理，直方图均衡，图像滤波，C++编程，还有一下其它的人脸检测的背景知识。-Face expression identification code, part of the realization of the algorithm and write the purpose of this paper is to provide a I development of SSE optimized, c++ library for face detection, you can get it for your video monitoring system. Regarding technical: wavelet analysis, dimension reduction model (PCA, LDA, ICA), artificial neural network (ANN), support vector machine (SVM), SSE programming, image processing, histogram equalization, image filtering, c++ programming, and the other face detection background knowledge.
