Unpaper - extrat text and images from scanned pages

Post by jumpjack » 02 Jan 2011, 12:12

Do you know this software?
http://unpaper.berlios.de/unpaper.html

It looks quite cool... but ubfortunately it's linux only: does anybody of you know how to use it on a Windows VirtualMachine running Linux? I'm not skilled at all in Linux, so I'd need a pre-compiled binary, but I don't even know if it exists...
How can I use Unpaper in Ubuntu, for example?
Ore does any similar program exist for Windows platform?

Isn't this what Scan Tailor does, except with a GUI and a Windows build? I would like the despeckling, but that's already been refined quite well in many other applications.

Unpaper certainly fills the same niche as scantailor, but they do have slightly different feature sets. For one thing, unpaper is run from the command line and could be worked into a more automated software flow than could be done with scantailor. Unfortunately, in my experience unpaper has been very reliable in giving me very poor results, especially compared to scantailor. Of course, I've never invested much time in working with it either...

Get yourself to a command line (probably applications->accessories->terminal or the like). To install unpaper: "sudo apt-get install unpaper". To use it, move to the directory that contains your images (e.g. "cd ~/directory_with_scans") and then "unpaper input_file output_file".

The documentation you linked to should help you understand the available options. You can also read the manual with "man unpaper".

I was thinking the exact same thing. I am working on a scanner design which downloads the images directly from the camera each shot. This could be useful for pre-ST processing (as it gets confused when I have tons of edges). I might use this too.
