Thanks for your answers, sorry for being a bit impatient. I'm using tesseract 3.0 (latest version on Fedora 17), but it looks like openwrt has tesseract 3.031 packaged as well I'll try to do ocr on the embedded machine if it can handle it, if not then I'll do it on my home server.
I used uncompressed tiffs saved in latest GIMP 2.8, I'll also try command line imagemagic maybe there is some issue with GIMP, but as you managed to read them on tesseract 2.04 maybe there is an issue with tesseract 3.0 not liking these tiffs for some reason? I'll keep you all updated on my progress. Cheers, Valent. -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
