optical character reader

Optical Character Recognition (OCR) is a technology that scans and identifies printed text or numerical data. It eliminates the need to retype existing printed material for data entry. OCR software works by comparing the shapes of characters to those stored in its library. It also considers character proximity to identify words and attempts to reconstruct the original page layout. High accuracy is achieved with clear scans of good-quality originals, while accuracy decreases with lower-quality originals or scans. OCR is an abbreviation for optical character reader or optical character recognition.12
