Creating test data with Octave
==============================

Octave-Forge needs to installed (with image package).

1. Start Octave
2. Change working directory to where the test data is located
3. Execute the commands:

   load cross.dat
   D = imsmooth(C, "Gaussian", 4)
   save cross_octave_smoothed_4.dat D
   E = imsmooth(C, "Gaussian", 8)
   save cross_octave_smoothed_8.dat E

   load cross_tiny.dat
   U = imsmooth(T, "Gaussian", 2)
   save cross_tiny_octave_smoothed_2.dat U

   The Gaussian S.D. is 4 and 2 pixels, respectively.

4. Convert resulting dat files to images with asc2flo and flo2ecat as normal.
