Software to clean up photos of whiteboards and documents? [closed]

Software to clean up photos of whiteboards and documents? [closed]

I take a lot of photos of whiteboards, blackboards, and so on for teaching purposes (examples online through May 2010). I'm interested in cleaning them up for archival purposes, preferably using Linux. Commercial products ClearBoard and PhotoNote are priced a little aggressively for my purposes, plus my students would like to have this capability too.

"I use JotNot on my iPhone which is pretty amazing (and only cost $1 for full version I think). Simple image capture, with several processing/correction presets and then export to JPG or multi-page PDF.

Wish there was a Windows version though. :-(

"When it comes to command-line image processing on Linux, I have to admit ImageMagick is king. It's free and open source, of course :)

It sounds like the main thing you'd like to achieve is sharpening and lessening the amount of colors used in the image.

For example, to convert an image to 256 colors:

convert input.png -colors 256 output.png"
