I'm experimenting with zonal OCR, but I've noticed that the OCR tends to interpret many non-existent characters, especially in marked areas where the text ends before the predefined marking.
I thought about combining some ImageEn functions to try and solve this. See if this is a good approach, and if you could provide an example, I would be grateful.
I was thinking of converting the selected area to black and white to improve OCR reading, then sending only the selected area (already in black and white) to detectTexts, and then generating the OCR on the detected text.
Do you think this is a good approach? Could you contribute some ideas and an example?
Certainly, limiting the OCR to a specified zone markedly improves the result, but the problem is finding a way to make the process automated. I think you would be best to review the Tesseract (IEVision uses Tesseract 5) forums to see what advice they offer.
