How to improve the recognition of receipt (text not in words dictionary)

[Laura]

Hi, I’m new on tesseract. I’m trying to recognize receipts. Since on receipts, lots of text are not dictionary words. I disabled the dictionaries,  it increased the recognition rate, but it’s still low, I’d like to create my own dictionary with the product catalog.

Is there someone who can give the tutorial to do it ?

Many thanks !

Laura

Please see https://github.com/tesseract-ocr/tesseract/issues/960#issuecomment-305966719

on stable 3.0x you can try by adding your product catalog to eng.user-words file and check for improvement.

In my unit test, it seemed to apply the words from user dict.

Alternately, you can also try withthe development version tesseract 4, --oem 1 directly - I don't think user-words work with it, but it might give you better recognition.
