查看 OpenCV 库，这里有一个关于它的优秀 wiki 的链接。
在这里您可以看到实现人脸识别应用程序的示例程序。
Check out the OpenCV library, here is a link for a good wiki about it.
And here you can see a sample program of implementing a face recognition app.
人脸识别被定义为将给定的未知人脸图像与一组已知人脸图像进行匹配的问题。 你要找的是人脸检测，用谷歌搜索一下，你应该会找到很多。
Face Recognition is defined as the problem of matching a given unknown face image to a set of known face images. What you are looking for is Face Detection, google it and you should find plenty.
这不是完整的答案，但可能会有所帮助。 特征向量也用于人脸识别：eigenfaces。
This is not a complete answer but it might help. Eigen-vectors are also used in face recognition: eigenfaces.
