Characters are then identified using one of two algorithms: OCR programs can vary in their techniques, but typically involve targeting one character, word or block of text at a time. The dark areas are then processed further to find alphabetic letters or numeric digits.

The scanned-in image or bitmap is analyzed for light and dark areas, where the dark areas are identified as characters that need to be recognized and light areas are identified as background.

Once all pages are copied, OCR software converts the document into a two-color, or black and white, version. The first step of OCR is using a scanner to process the physical form of a document. Once placed in this soft copy, users can edit, format and search the document as if it was created with a word processor. The process of OCR is most commonly used to turn While software typically handles the advanced processing.Ĭan also take advantage of artificial intelligence ( AI) to implement more advanced methods of intelligent character recognition (ICR), like identifying languages or styles of handwriting.

OCR is sometimes also referred to as text recognition.
