The main difficult thing for you will be any characters that are not already trained. There's no easy way to "just add a few characters" you basically have to do a full retrain. If you're okay living within the unicharset already trained for a given language, you can just swap in your own dictionary files, either using combine_tessdata(1) and wordlist2dawg(1) or by specifying a user-words file (to augment the dictionary) described as zdenko mentioned on the man page. -david http://tesseract-ocr.googlecode.com/svn/trunk/doc/combine_tessdata.1.html http://tesseract-ocr.googlecode.com/svn/trunk/doc/wordlist2dawg.1.html http://tesseract-ocr.googlecode.com/svn/trunk/doc/tesseract.1.html -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
