Often abbreviated OCR, optical character recognition refers to the branch of
computer science that involves reading text from paper and translating the
images into a form that the computer can manipulate (for example, into ASCII
codes). An OCR system enables you to take a book or a magazine article, feed it
directly into an electronic computer file, and then edit the file using a word
processor. All OCR systems include an optical scanner for reading text, and
sophisticated software for analyzing images. Most OCR systems use a combination
of hardware (specialized circuit boards) and software to recognize characters,
although some inexpensive systems do it entirely through software. Advanced OCR
systems can read text in large variety of fonts, but they still have difficulty
with handwritten text.
The potential of OCR systems is enormous because
they enable users to harness the power of computers to access printed documents.
OCR is already being used widely in the legal profession, where searches that
once required hours or days can now be accomplished in a few seconds.
