OCR Full Form - Optical Character Recognition
OCR stands for optical character recognition. It is also known as an optical character reader (OCR) or text recognition. It is designed to convert scanned paper documents, or images of documents captured by a digital camera into readable, editable and searchable data.
The scanned page of a physical document can be displayed on the screen and can be read, but for the computer, it is just a series of black and white dots, which it cannot recognise. To enable the computer to read a scanned document and produce a soft copy, OCR was developed. OCR examines the text of a scanned document and translates the characters into code that makes the text machine-readable so that it can be transformed into an electronic format or soft copy just like a document created with a word processor which users can edit, format, search and read.
Thus, it helps computer recognize words and characters on a scanned page or digital images of physical printed or handwritten documents by using the optical properties of words and characters printed on a scanned page or document.
An OCR device is made up of hardware and software combination, designed to convert physical documents into machine-readable text. Hardware of OCR (optical scanner or a circuit board) copies and reads the text, whereas the software deals with the advanced processing. The software can also make use of artificial intelligence to use advanced methods of intelligent character recognition (ICR), like the ability to identify language or style of handwriting.
