Where can I find facial detection software, algorithms, etc? [closed]

Question

I'm interested in writing software that depends on being able to identify that there is a face in a picture (or video frame). It doesn't have to ID the face - so no metrics other than:

• Is there a human face in the picture (or more than one)
• Where, approximately, are the eyes and mouth or nose tip (whatever it keyed on.)

It's popping up in cheap digital cameras now, so I expect there are open source packages that do this, or research that is easy enough to follow when rolling your own.

Answer 1

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.
