This is an overview, made mainly for developers. You can find typical example files made by me and sent by others. You can pick a example and try to improve gocr. Note that the other examples should be recognized like before your changes or even better.
Users can get a first impression here of how well gocr works.
Only errors, where good readable characters are not recognized, or completely wrong recognized are counted. Sometimes missing accents are also not counted. Take it as a rough overview. It is also counted by hand, so it is not very exact.
