Hey! Camelot maintainer here. You can check out this doc for details on how Camelot extracts tables from PDFs: https://camelot-py.readthedocs.io/en/master/user/how-it-work...

As pointed out in this thread, right now it only works with text-based PDFs. But there's a PR[1] which will add OCR support (using EasyOCR) for image-based PDFs in some time.

[1] https://github.com/camelot-dev/camelot/pull/209

From the link: "Camelot only works with text-based PDFs and not scanned documents." If you have character data, using it is almost always going to be more accurate than OCR.

I don't know how OP uses it with images converted to PDFs though, as that would be just like a scan, and ImageMagick doesn't do OCR as far as I can tell.

It uses pytesseract and Open-CV, so there is image processing.

Looks like it's a bit in-progress: https://github.com/camelot-dev/camelot/pull/209

"Update docs" isn't checked, and that's what I was going on.

Yes I need to work on that PR, haven't been getting a lot of free time these days. It adds OCR support using EasyOCR, which I found on HN some time ago!
