providing your picture is black text on white backround it seems to work pretty well.

i'm wondering how hard it would be to write a 'sharing' plugin for the photo manager, which will just call a script to process the image through convert and tesseract and spit out the text.

if i get the time I'll play more. might be cool if someone with a setup for packaging would consider uploading tesseract and magemagic to extras-devel....
I was gonna do the same thing, but did not get around to it yet.
I also use unpaper when automatically processing scans on server.

it is a small program but helps a good bit with tesseract ocr

i tie together some imagemagick->unpaper->tesseract with pretty great results and insert the raw text output into db as metadata for searching docs on our server.

works pretty well.
