Appeal No. 94-3823 Application 07/812,249 The Invention The invention is directed to machine recognition of color- coded alphanumeric characters. Such recognition occurs because the characters differ in geometries and because they contain differing color pixels. More specifically, each alphanumeric character has a predominate color, e.g., black, which applies to the whole character. This predominate color is readily distinguishable by humans. Each character also has a non-predominate color which is intermingled within that character's predominate color and is non-distracting to humans. The non-predominate color, however, is distinguishable to and can be detected by a color scanner. As disclosed, each non-predominate color represents a separate character. Thus, when the scanner recognizes a particular non- predominate color, it can then readily recognize the character associated with that color. In addition, the machine senses the geometry of a character to determine which character has passed. Claim 1 is directed to a method for recognizing the above- discussed geometric color-coded characters by using a first character recognition system which views the particular 3Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 NextLast modified: November 3, 2007
