I used tesseract/pytesseract, almost perfect pre processing using blur, otsu etc,
But for get good results, you need big images, 300 dpi+ are needed,
The big images make it is too slow,
Maybe i should have try segmentation the caracters before using the ocr,
I endeup making my ocr from scratch, using averages etc, and it is almost instant, and i am happy with it.
- ejanus 9y agoI am currently trying out tesseract/pytesseract on shop receipts but I have not being able to get meaningful result . I have tried adaptive Gaussian and mean threshold, I have also tried blur . But no joy yet. You mentioned building from scratch, how ? And what is your minimum size ?
