These applications include multimedia systems, digital libraries, and Geographical Information Systems.When machine generated text is printed against clean backgrounds, it can be converted to a computer readbleform (ASCII) using current Optical Character Recognition (OCR) technology. However, text is often printedagainst shaded or textured backgrounds or is embedded in images....
