Hello,
We've consistently noticed an issue with Azure OCR in which the service returns a JSON that concatenates words from two separate document lines. It's extremely unpredictable and leads to a lot of issues that we can't fix or foresee and repair.
For example, on the image of a PDF scan there are 3 lines in three different languages. Azure OCR on one occasion returned the text "FRACHTBRIEF SAMOCHODY" as a valid read in the JSON, on a different occasion it returned "CONSIGNEMENT SAMOCHODOWY".
Is there a way to configure how will the lines be concatenated?

2024-11-20T10:00:01.27+00:00 Yes, I've attached a PDF file of an unfilled form in this comment. Obviously the quality is a bit higher, due to this file being a template and the files we receive being scanned paper documents, but I don't think it makes a lot of difference in this case.
