推荐答案

这是一篇关于面部检测的文章，可能对你有所帮助： C＃中的人脸检测 [ ^ ]

Here's an article on face detection that might be of help to you: Face Detection in C#[^]

可以使用Haar分类器检测面部。如果你想在C＃中使用它，我可以发给你源代码。人脸检测演示可在

希望这将有所帮助

Face can be detected using Haar classifier. If you want it in C#, I can send you the source code. The demo of face detection is available at

有三个阶段，包括人脸检测，特征捕捉，人脸识别。第一个是basic.You可以使用OpenCV进行检测。但我更喜欢 Face ++人脸检测API 。它支持Java，C＃等。随着更大的图片，它会带来更好的结果。

我刚刚将Face ++与OpenCV进行比较。考虑到检测和识别，Face ++ API似乎更好。

There are three stages including face detection, feature capturing, face recognition. The first one is basic.You can use OpenCV to do detection. But I prefer Face++ face detection APIs. It support Java, C# and so on. With bigger pics, it comes better results.
I have just compare Face++ to OpenCV. It seems Face++ APIs are better considering detection and recognition.
