* This is the main class of LEA.
* <p>
- * It uses a face detection algorithm to find an a face within the provided
- * image(s). Then it searches for the eye in a region where it most likely
- * located and traces its position relative to the face and to the last known
- * position. The movements are estimated by comparing more than one movement. If
- * a movement is distinctly pointing to a direction it is recognized and all
- * listeners get notified.

* The notification is designed as observer pattern. You simply call
- * <code>addEyeMovementListener(IEyeMovementListener)</code> to add an
- * implementation of <code>IEyeMovementListener</code> to LEA. When a face is
- * recognized/lost or whenever an eye movement is detected LEA will call the
- * appropriate methods of the listener

+ * movement is detected LEA will call the appropriate methods of the listener

- * LEA also needs an image source implementing the <code>ICaptureDevice</code>.

- * This will start LEA with the first available JMF datasource with an extra
- * status window showing if face/eye has been detected successfully. Please note
- * that face detection needs about 2 seconds to find a face. After detection the
- * following face detection is much faster.
