     This tool supports two operation modes. 
         - Use face-detector then tracker on every frame (accurate but slow as face detector is the slowest component, 60ms in total per frame).
-        - Use face-detector only in first frame, and a combination of tracker and pseudo face-detector afterwards (fast 4ms in total per frame).
+        - Use face-detector only every n-th frame. 
+          In between detector frames, a combination of tracker and mock face-detector (fast 4ms in total per frame) is used.
 
     This application uses OpenCV capture device to open the input device. As such it supports web cams and video files.
     During execution press any key except 'x' to trigger a new face detection.
