Chessboard data

Here are files for the image data ("chessboard" image) used in

A.J. Baddeley. Errors in binary images and an L^p version of the Hausdorff metric.
Nieuw Archief voor Wiskunde 10 (1992) 157--183.
A.J. Baddeley. An error metric for binary images. In W. F"orstner and S. Ruwiedel (ed.), Robust Computer Vision: Quality of Vision Algorithms, Proceedings, International Workshop on Robust Computer Vision, Bonn 1992. Karlsruhe: Wichmann, 1992. pp. 59--78.

All are TIFF files (big-endian) suitable for Silicon Graphics machines.

Unfortunately I didn't save the images which were generated by adding Gaussian noise to the true chessboard image, as that was all done on-the-fly.
