Best image pre-processing software

[Chris Smeal]

I've been doing some research on using Tesseract for both document scans and text in scenery, and I was wondering what image processors are best?  Given I have a lot of images, I cannot process each batch by hand, so I will have to make a pretty smart pre-processing app before I get started.  This will be developed against a Linux OS, so right now I am looking at:

Leptonica

ImageMagick

OpenCV

GIMP

ImageJ

I also thought about unpaper or scantailor, but the level of documentation is pretty small relative to the above technologies, and I highly value strong documentation support.

Any thoughts which of these are best, or if I am missing anything obvious?

Thanks for your help.

Sounds good to me. unpaper and scantailor are nice, but everything
they do should be well covered by your choice of tools.

I like the GraphicsMagick fork of ImageMagick because the documentation is better and it is faster. It can be automated using the PerlMagick API.
