Face detection using neural networks

My first idea was to use my neural network library to recognize people using a webcam but the first problem I had was to find the face in the entire image coming from the video capture device.
After searching on the internet I found a method to detect face using neural network (you can find those documents on my links page) so I tried to implement it in C#.

As you can see it's not perfect at the moment but it's only the begining !
