Zafer has created an awesome webcam application to track your eyes with C++. The project has 3 parts, face detection, eye detection and eye feature extration. Zafer uses two different methods for the face detection too! He implemented a Continuously adaptive means-shift algorithm and a Haar Face detection method. Zafer explains what that actually means in English so even I could understand it … kind of.
Wish there was a video of this in action.
