A Review on Optical Character Recognition

Nowadays, using a keyboard for entering data is the most common way but sometime it becomes more time consuming and need lots of energy. So, a technique was invented named Optical Character Recognition abbreviated as OCR that transfigures printed as well as handwritten text into machine encoded text by electronic means. OCR has been a topic for research for more than half a century. It electronically and mechanically converts the scanned images which can be handwritten, typewritten or printed text. In general, to figure out the characters of page, OCR compares each scanned letter pixel by pixel to a known database of fonts and decides onto the closest match.

Keywords

optical character recognition processed pixel scanned document machine encoded text.
