I spent many afternoons trying to get tesseract to read Dwarf Fortress screenshots, such as http://i.imgur.com/32vVhnH.png http://i.imgur.com/32vVhnH.png - including much pre-processing, such as converting the text to black and white. Alas, I never even got close. Edit: just tried Google's, and it had one mistake for that entire file. That's pretty impressive.

  This seems like a font issue. Would training the model for this console font help?

Since we're trading "I failed" stories... I spent a weekend tying Tesseract together with Tekkotsu (the amazing open framework for the Sony AIBO) in an attempt to teach my robot dog to read. The eventual goal being to hook up the output of OCR --> Text To Speech (TTS) and have him read to me. Alas, the low resolution of the camera was an insurmountable problem. Poor Aibo needed 40-point fonts and I practically had to rub his nose in the book. Not exactly the user experience I was aiming for. Never got around to the TTS part.

  I completely missed the word "robot" then and was pretty impressed that you wanted to teach your dog to read.

    I'm trying to fathom how you thought he loaded Tessaract into a live dog.

      There are two openings. One accepts anything, really. It's dangerous to try to use the other one, though.

If you're reading screenshots of a non-changing font, you could quite easily get away with plain template-matching. Simply do a run through and label the data one time. I did something like that a few years ago when making an Eve-Online UI scraper.
