picture pdf to mobi/prc

Rflcrx · 10-27-2010, 06:07 AM

Hey,

Do you have any tipps regarding converting pdfs (which are picture based and have no text/text is picture only)? I tried calibre, pdfread, mobipocket..but the results are not good enough. I continued searching but this kind of conversation seems to be unpopular. I don't need a fast/easy conversation, the result counts, so I don't mind to converting in 10 steps. Any suggestions? I am kinda desperate, thinking about just typing the picturetexts down or giving up, so any advise would be greatly appreciated.

Cheers

assuming, you're referring to scanned books that are bound in a pdf file, what you need is a OCR-type software that will convert the scanned page into an actual editable text.
i can recommend ABBYY FineReader.
it works quite well, but as always everything depends on the quality of the picture because the worse the image, the more editing you'll have to do on the newly-converted text.
i know there are ways of editing the text in ABBYY but i'm not that savvy with the software. i usually run the scanned text through ABBYY, convert it to a .doc file and then spend quite a lot of time combing through it until i clear out most of the typos.
then you can use calibre to convert the .doc file into mobi.

Acrobat pro 9 is what I use... 300dpi scans and above generate spot on OCR with few errors, go recognize text with OCR. Then you can export it as txt/rtf/html (if it's just a simple book)

There's other software out there too, but if it's already a pdf, shrug.

New version of Nitro PDF has OCR so I've heard. There also may be other free software out there, not sure about the quality. Some more advanced OCR software I have used in the past allows fine tuning of OCR and imports of dictionaries and such. I think acrobat just uses standard dictionary for OCR correction, and it doesn't ask you to correct errors if it finds any

Good luck to you.
