Hi, sure, here you go:
http://roggisch.de/screenshots.tgz A little bit of explanation: On the right, you see the processed image with lines detected by OpenCV. At the end of the lines, you see the page-numbers, which are extracted and copied into the image in the left half, you can see that as well. In the terminal, you see the classification-results: the dictionary contains keys left and right, and as you can see, numbers vary wildly. Again, the very same code and setup works with really high accuracy if showing numbers from 10 to 28. I'm in the meantime trying to finde the original data for the english language training - are these available somewhere?
