Automatic colorization of monochromatic printer documents

摘要

Embodiments herein include a method of adding color to a monochrome (single color printing) document that begins by inputting/creating colorization rules (100) relating to the previously printed monochromatic document and scanning (102) the previously printed monochromatic document to locate rasterized data. After the scanning, the method performs optical character recognition (106) on the rasterized data to search for text corresponding to the previously printed monochromatic document. After the rules are input and the rasterized data is produced, the method automatically colorizes (110) portions of rasterized content according to the colorization rules and this generates a colorized electronic document.
