I'm using a low-budget scanner which gives a kind of blurry image. The contrast could be enhanced by just changing the colours (gray-shades (32)) of the pixels, but this doesn't improve the resolution, and loses a lot of details. If the solution is (relatively) simple, could you please mail it directly, because I'm not sure if I can get my hands on any old articles (although our CS library seems to have a lot of them).
