Patent ID: 8615137

Claim:
A method for determining a recognized pattern of an object in a single received original image in pixel format, comprising: dividing the single received original pixel image into a plurality of received image areas, calculating a plurality of area-specific reference values, one for each of the plurality of received pixel image areas, at least one of the area-specific reference values being based upon statistics of less than all of the sample pixel values in the respective received image area, at least one of the area-specific reference values being calculated based upon plurality of the sample pixel values in the respective received image area such that a total number of area-specific reference values is smaller than a total number of sample pixel values, employing only one comparison step which includes comparing at least one of the calculated area-specific reference values with only first reference values associated with a plurality of pattern parts of objects, and determining the recognized pattern of the object when two or more adjacent received image areas have area-specific reference values which correspond to two or more of the first reference values by a predetermined percentage.
