There are 2 steps: 1. text detection in the photo - IMHO this is the most difficult part. Try to search for "text detection in natural scenes". 2. text area processing for OCR 3. OCR.
E.g. with this image you can get quite good result with tesseract: [image: engraving.png] tesseract engraving.png - --psm 6 --oem 1 S601 25835 As you see only problem is the letter "G" detected as "6". Maybe better processing (step 2.) can fix it easily: Try to search this forum for "embossed", "engraved", swt. IMO there are several tutorials for OCR embossed credit cards, that could help you. e.g. https://www.pyimagesearch.com/2017/07/17/credit-card-ocr-with-opencv-and-python/ or https://stackoverflow.com/questions/9398374/prepare-complex-image-for-ocr Zdenko po 7. 2. 2022 o 13:29 PKD <prana...@gmail.com> napísal(a): > Hi, > > I have images where numbers are curved on a metal base.
