摘要:
A character recognition system in which a representation of a character is scanned along a plurality of scan lines and measurements are made based on the transitions in each scan line between areas of the character and areas of the background (6). For each scan line a vector is generated based on the transition measurements for the scan line. The vectors are selectively combined logically in order to identify the character (8).
