- * eye-tracking.cpp:
- * Eye detection and tracking with OpenCV
- *
- * This program tries to detect and tracking the user's eye with webcam.
- * At startup, the program performs face detection followed by eye detection 
- * using OpenCV's built-in Haar cascade classifier. If the user's eye detected
- * successfully, an eye template is extracted. This template will be used in 
- * the subsequent template matching for tracking the eye.
