So… Facial Recognition.

The second part of the project is to attempt to recognize faces.  Not just say that something is a face, but specifically, whose face it is.  This will be done in two parts.  First, it needs to detect a face in an image.  That should be fairly easy.  OpenCV has functions and data for face detection built in.  Then the recognition needs to happen on the detected face.  That won’t be quite as easy, because it’s going to involve training the system to figure out who is who.  In other words, the recognition phase will require actual work.
