       *   Functions: This file contains
       *      main
       *
       *   Purpose:
       *      This is a calling program that calls
       *      the three new segmentation techniques
       *      discussed in Image Processing part 10.
       *
       *   External Calls:
       *      imageio.c - does_not_exist
       *                  get_image_size
       *                  get_bitsperpixel
       *                  allocate_image_array
       *                  free_image_array
       *                  create_file_if_needed
       *                  read_image_array
       *                  write_image_array
       *      segment2.c - edge_region
       *                   gray_shade_region
       *                   edge_gray_shade_region
       *
       *   Modifications:
       *      5 December 1992 - created
       *      15 August 1998 - modified to work on entire
       *           images at once.
