What is OCR ?
OCR (Optical Character Recognition) is the recognition of printed or written text characters by a computer. This involves photoscanning of the text character-by-character, analysis of the scanned-in image, and then translation of the character image into character codes, such as ASCII, commonly used in data processing.
Or, we can say... Optical character recognition (OCR) translates images of text, such as scanned documents, into actual text characters. Also known as text recognition, OCR makes it possible to edit and reuse the text that is normally locked inside scanned images. OCR works using a form of artificial intelligence known as pattern recognition, to identify individual text characters on a page, including punctuation marks, spaces, and ends of lines.
