Why We Need Optical Character Recognition (OCR) Technology?
What should you do if you want to convert scanned paper, books and documents into electronic files like Word document, PDF, or text? You need Optical character recognition, usually abbreviated to OCR, which can translate scanned images of handwritten, typewritten or printed text into machine-encoded text.
OCR technology makes it possible to search for a word or phrase in an image, scanned PDF or other un-editable file. Once you extract text from image, you can store it more compactly, send it to Google to translate text, put text into text-to-speech techniques, or publish the content on your blog or website.
Indeed, countless of scanned documents are produced every day. All you need is just a scanner, a wonderful tool that is the reverse of printer. A printer can make digital text into physical paper, while a scanned turns physical paper into digital picture. Although you might find that the scanned text looks the same as the normal digital text in your screen, there are lots of differences between them.
For example, you are not able to search the words or phrase in scanned images. The computer will not recognize that. Picture is almost unintelligible for computer. But machine-encoded text is searchable, and can be easily recognized. And changing the content of scanned text is a lot more difficult for many users. If you produce PDF after scanning, you need OCR PDF editor to edit the content. If you got image format after scanning, you need to have the skill to edit the images.
Things would be much easier with OCR PDF converter.
