In the input image, the storm near the equator on the planet Saturn is hard to see. In the output image, the storm is much more visible, as the edge detection algorithm has removed extraneous detail. To test the function, we need a main program. The graphics produced by this standalone program are identical to those produced by the first example, shown in Figures 1a and 1b.
