I did this back in 2012, using Tesseract and OpenCV to scan letters from screenshots.  I did it in python, though, but it was relatively straightforward.  I actually had to create my own &quot;language&quot; to help with the processing, bringing it from the low 90s to ~98% accuracy.<p>It doesn&#x27;t diminish OP&#x27;s work, though, nice job.
