Laboratories need to be funded and built. Theories need to be tested. Iterations need to be computed. All I can think is your reality must be nothing but fuzzy blurry smooth objects. The image, named Contests.gif is a 640x480x256 file using only 52k of valuable web space.
Slight roughness is apparent around the contour edges.
Otherwise there is little to improve with this image by filtering. However, if there can be a reduction in file size, that would make it well worth it. The resulting 1137kB gif file was loading into Xnview v1.05b and converted to a Truecolor jpeg. It weighs in at a hefty 152kB but does have smoother contours. Perhaps I can catch Dr. J in some activity involving thin nearly parallel line patterns next time.
