title: Face detection algorithms
body: <p>I am trying to make an application for my graduation thesis which consists in the implementation of a face detection and recognition algorithm to detect the faces of individuals in a room with a video camera. So I'm looking for a "not so hard" algorithm that detects frontal and profile face, then a face recognition algorithm and use it with a face database.
  So far I have found the Viola Jones algorithm and KLT algorithm. I don't want to use any API.
  If anyone knows I would be grateful. Thanks</p>
