As in this post: pytesseract using tesseract 4.0 numbers only not working Described, its possible to detect numbers with the eng.traineddata file but if I want to detect only numbers, this isn't possible with this file. Even if you define tessedit_char_whitelist=0123456789 it doesn't recognize anything.
- I searched on GitHub and so on to find a digit.traineddata for Tesseract 4.0 but didn't found one? Does someone know which one I could take?
- Is it possible to use one from Tesseract 3.x (but also found nothing there)
- Is it complicated to train my own dataset only with numbers, what would be the way to do this?
