Is there a better way to remove the 'halftone' dots then by using Bur in the GIMP? I don't have access to Photoshop.

try using texture or edge preserving smooth.
that or duplicate + gaussian blur + softlight layer

Heavy doses edge-preserving blurs tend to help with cel-like character illustrations with strong lines and solid colors (in other words, not this one)

What does help though (and Gimp probably does something similar) is to put a heavily blurred duplicate layer on top and to set the blend mode on "color"... this removes the chroma noise.

The Gimp is an impressive bit of software for being freeware - however, it really can't compete with Photoshop combined with a good noise reduction plug-in.

Ugh, yours looks painfully oversmoothed, but I guess this is one of those personal preference things. (And still has a crapload of impulse noise.) A characteristic canvasy look is way less objectionable than that.

Everytime one of these threads come up I come up with a new way of tackling it with the experimental noise removal filters my friends are always sending me. This came out pretty good, for 15 minutes of experimentation, although they have some memory leaks and quit previewing properly after a while. >.> It's got some obvious problems, but I won't really look into it until the next time. :p It's hard to figure out what to keep when the thing has more halftoning than actual detail.

Looking at mine again, it looks a little _too_ much like canvas - cracking paint on canvas. That wasn't intentional, stupid filters, although I'll admit it's neat.

Don't you like missing thumbnails? Anyway, this is the second cover, the other (the PoFV one) is already posted at MOE.

Actually, I feel the same way. I intentionally over-filtered it to illustrate how well it is able to remove the noise. With a little more time fine tuning the sampling and a little hands-on editing you can get the same level of noise reduction without the loss of fine detail. Reducing noise starting at the scanner is generally best. Many scanners have excellent descreening filters.

There's still a lot of chroma noise, but yours looks the best overall. What method did you use, if you don't mind sharing?

greycstoration_win32.exe -restore "C:\Documents and Settings\Administrator\Desktop\1172953342823.jpg" -ns 0 -nu 0 -ng 0 -scheme 1 -iter 1 -sigma 0 -alpha 2.0 -a 0.1 -p 0.1 -dt 1

google for greycstoration

Highly tweakable filter for image clean up..it just takes alot of tries to figure out the best for what type of noise. Also read the documentation.

If you use greycstoration, you might want the GUI:

Not necessary, but it's a little simpler to use. (Lack of drag-n-drop kind of impedes it.)
