OCR, sounds like a hiphop group but in fact it is object character recognition. The electronic translation of handwritten, typed or printed text images.
It may be that you’ve came across this since it is a very commonly used concept. I’ll briefly explain what is it and why it is used. It may come handy for you as well.
Generally this is used to convert books and documents into electronic files. This to digitalize the documents in an office for example. As you know, a USB stick takes less place on your shelve than a book does ;-).
Since OCR is a scanning technique which converts written text to digital text, this means it will also allow you to edit the scanned text, perform searches in it, mail it to other people.
Interesting to know if that OCR software is analytical artificial intelligence that consider sequences of characters rather than whole words or phrases.
In other words OCR makes “best guesses” using a database.
So, the basic idea is, you scan an image, process it with OCR software, you receive a digital, editable document of your scanned image.
There are lots of software packages for OCR. Here are a few:
