Hi Dani,

 

you can try with the various settings you find in image processing, for example this result:

we obtained using: 

  1. Min filter to 3
  2. Auto color level
  3. Intensity Detect

And the result of OCR:

DATE12/07/2021 DEBIT

FACTURE NO 1049166

 

However it is only a test with your jpeg attached, so for sure with a high quality document the output results can be better. 

If you need specific help with your documents we suggest you contact our support for sure they will be able to suggest and direct you on the right way cool.

 

Best regards,

Luca
