Video: Real-time Face Tracker on Nokia N900

Dr. Philip A. Tresadern at the University of Manchester has revealed a real-time face tracker on the Nokia N900 mobile phone. The aim for the research is to do both face and voice verification using the camera and microphone built into mobile phones for secure access to apps without passwords.

Using a technique known as the Active Appearance Model that was pioneered by the University of Manchester, the face tracker use landmarks on the face (e.g. around the eyes, nose, mouth and jawline). The positions of these landmarks relative to each other define the shape of your face and indicate where you are looking, your expression and who you are. Video follows after the jump.
