Libre OCR

shevirsy · 09-12-2014, 05:31 AM

I have a few PDFs made from library scans of rather old documents. The fonts look to me like those of today. The scans are not excellent, but they are made with a flatbed scanner and not those ripoffs with a camera where the page is twisted and you see a hand peeking from one side.

Do you have experience with libre software? Do you know tutorials or forum posts that can explain to a newbie? I have experience working with graphics. Not with OCR.

I have no knowledge of a good free OCR tool that even comes close to commercial ones.

I have missed that thread where the OP asks "Do you have knowledge of a libre software pack that is better than the closed source counterpart".

Anyway, I have asked something different. You might reread.

Try Tesseract. Not very user-friendly and probably not for newbies. And as Toxaris said, you won't get very much in the quality department.

As for the questions you asked: Yes. No.

I have tried it. In terms of usability is on the opposite side of Abbyy Finereader. Sad.

The k2pdfopt program can do OCR on a scanned PDF using tesseract. It can even embed the results into the PDF file as a text layer. k2pdfopt has a zillion options, so I'm not sure it's easier to use than bare tesseract, but you can try it for nothing and see.
