ocr metadata

[hakankaraoguz]

Hi,

When using auto partitioning to partition pdfs, is it possible to get ocr metadata (quality, used or not etc) when pdf parser falls back to ocr strategy?

Hi @hakankaraoguz

Can you please share the code you're trying and more details about the OCR metadata you want to get?

Hi @christinestraub
According to documentation if auto strategy is used , there is no indicator in the element metadata when unstructured falls back to OCR strategy. However here I can see that OCR confidence is extracted in pytesseract. I would like to have the OCR confidence information present along with a strategy flag in the element metadata so that I can filter out low quality text after parsing stage.

Any updates on this?

@hakankaraoguz Did you try with hi_res strategy? Is the detection_class_prob metadata field not working for your case?

I will try it out but according to this Article detection_class_prob is about the class confidence of the extracted section (Table, Header etc) in the PDF. I am more interested in having the OCR quality result if the algorithm falls back to OCR. Thank you @christinestraub
