Recovering redacted information from pixelated videos
Not off the shelf but here are some tools. I have no experience with them.
Wolf binarization - I think it makes the text more clear before OCR.

Show HN: Pystitcher – A Declarative Alternative to Pdftk
i recently transitioned a large PDF processing pipeline[1] away from PyPDF3 to use the pikepdf[2] library instead. pikepdf is based on the C++ `qpdf` library, and this switch has cut the necessary special-case manual checking + error handling in half compared to pypdf for these sorts of tasks.
[1]: i'm helping out with the CV Open Access archive, https://openaccess.thecvf.com/menu. broadly, our pipeline needs to ingest tons of author-provided PDFs of varying quality and output a canonical PDF with corrected page numbers, proper metadata, and a banner stamped on the first page. it's a lot of work, and it's not uncommon for pypdf to simply fail for slightly invalid input or give garbled results. this isn't optimal since we can't review 2,000 papers per conference release lol. pypdf has been nice, but pikepdf has handled everything i've thrown at it.
