Hi all, first thank you for super software and FAQ on how to install it - went smoothly.
The question is though, maybe anyone has any tips on how to prepare image for tesseract? I've read the FAQ on borders, resolution, etc, but i have one particular scenario were image prepared on my Mac with Preview works almost flawlessly (considering how bad the original jpg is) and if i try to do the same on linux machine with imagemagick convert function, the results are disappointing . Currently i have an image - http://dl.dropbox.com/u/12535857/tesseract/sample.jpg If i convert it on my Mac and apply auto-levels i get image like this http://dl.dropbox.com/u/12535857/tesseract/mac.tiff which is finely transformed into text like this: ‘or the short pastry: a|1.purp0se flour, 1% 613:5 more as needed stick) unsalted butter Z/6 cup sugar 5 egg yolks Salt l4 lb.

Tried playing with contrast, but that doesn't seem to help. Thanks! -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
