It is (usually) easy for the human eye to detect the characters but virtually impossible for machines. This failure on the machine's part is the reason that form spam software works so well (often referred to as "Captcha"). But many errors are recognized words or they are in names that are ignored by the spell checker.Īnother reason machines fail is because of poor quality scans/images, small text, unorthodox fonts, and generally not being able to recognize letters from its rather limited library of knowledge on how to recognize letters. Fortunately, this is an error that any decent spell checker would pick up since "ivill" is not a recognized word. Therefore, if the image looks like an "iv" to the software, it will interpret as "iv" even though in context it might be "We ivill succeed and we will prosper!" This is not a real brain-buster for humans-not even an 8-year-old one.
In a 100,000 word book, this means you will have 100 messed up words! Not very professional, and quite a nightmare.Īt the time of this writing, OCR software used to convert scans into text do not contain enough AI (artificial intelligence) to have a good contextual understanding of words. Assuming a clean scan of the pages, even the best OCR software at 99.9% accuracy will screw up 1 out of 1000 words. To understand the image as text, OCR (optical character recognition) software must be run on the image to interpret the image as text. The software interprets the page as an image and not text. But creating a PDF from scanned book is like taking a photograph of each page. When you save a Word doc as a PDF file, there is far less of a loss in information, meaning that reverse conversion from that PDF back to the Word document will still have some issues, but issues that are not too difficult to address, and thus a relatively painless experience. If this is the case, I can virtually guarantee you that the PDF files you are working with are PDF files made from editable document files (such as Word) with very few advanced layout features (i.e., callouts, wrapped images, etc.) and not PDF files made from scanned images. Perhaps you convert PDF to Word documents on occasion and never had much of a problem. If you are not sure, read on! PDF to Word: Relatively Painless Experience. This article assumes that you already have a Word document that was created from a.
