Ocr meaning

ōsēär
(Optical Character Recognition) The machine recognition of printed characters. OCR systems can recognize many different fonts, including those designed specifically for optical recognition as well as typewriter and computer-printed characters. Advanced OCR systems can recognize hand printing.From Bitmaps to ASCIIWhen a text document is scanned into the computer, a picture is taken of each page. Just like a digital photo, the page becomes a bitmapped image of pixels. OCR software then analyzes the light and dark pixels in order to recognize each letter and digit, which is converted to an ASCII character. See bitmap, ASCII file and pixel.Hand printing is much more difficult to analyze than machine printing. Old, worn and smudged documents are also problematic. OCR is sometimes as much an art as it is a science.
