Abstract
Method of, and apparatus for, processing a color coded character to recognize the character being examined by an OCR device. Said color coded character comprises a predominate color associated with said character distinguishable by humans, and a non-predominate color associated with said character and non-distracting to humans, but distinguishable by a color scanner. The present invention allows the non-predominate color of a character to be used as the sole criteria for recognizing the character.
Claims6
A method of processing a set comprising color coded first and second characters for optical character recognition, wherein each of said first and second characters have unique geometric shapes formed by a first color with said first character geometric shape being different from said second character geometric shape, so as to define said first character relative to said second character when visually identified by a human, said first character geometric shape having one or more pixels of a second color, said second character geometric shape having one or more pixels of a third color that is different than said second color, said second and third color pixels being distinguishable by a color scanner, comprising the steps of:
- scanning said second color pixels and said third color pixels;
- and
- processing said scanned second color and said scanned third color.
An apparatus for processing a set comprising color coded first and second characters for optical character recognition, wherein each of said first and second characters have unique geometric shapes formed by a first color with said first character geometric shape being different from said second character geometric shape, so as to define said first character relative to said second character when visually identified by a human, said first character geometric shape having one or more pixels of a second color, said second character geometric shape having one or more pixels of a third color that is different than said second color, Said second and third color pixels being distinguishable by a color scanner, comprising:
- means for scanning said second color pixels and said third color pixels;
- and
- means for processing said scanned second color and said scanned third color.
The apparatus of claims 5 or 6, further comprising:
- means for processing said first color.
