We created a number of sample images (150 of each category) taken by
the new EyeCams using RoBIOS 2.3k.  The categories are no ball, still
ball and moving ball or robot.

All image files are successively numbered:
  ball_000.ppm  with  ball_000.txt
  ball_001.ppm  with  ball_001.txt
  ... and so on.

To each image file (format ppm), we created an ASCII text file with
information on the image data, consisting of 3 lines:
1. Line: 0 = no ball in image, or 1 = ball (resting),
         or 2 = moving ball or moving robot
2. Line: Ball coordinats in x (0..79) and y (0..59)
3. Line: Ball size in pixels

Example:
  1
  56 25
  16

The idea is now to use images+data for training a neural network that
should recognise the ball.
