Optical Character Recognition
(OCR, sometimes /oh'k*/) Recognition of printed or
written characters by computer. Each page of text is
converted to a digital using a scanner and OCR is then
applied to this image to produce a text file. This involves
complex image processingalgorithms and rarely achieves
100% accuracy so manual proof reading is recommended.
