So i installed tesseract, and running opencv3. I'm really excited to try out OCR. I tried out the webcam example in the text module, but all i get is a black stripe (the camera does turn on, see below for output). I also found this great thread about getting at least the ROI, and then maybe use something like gettext (can't use, GPL) to extract the text.

I'm really in the need for something that extracts texts from the webcam, like so : https://www.youtube.com/watch?v=pgth0... https://www.youtube.com/watch?v=Yv6Ik...

Or just by me feeding it a Mat or a ROI. Did anyone have any success with that?
