Abstract
A method of operating a pattern recognition apparatus comprises generating a plurality of sub pixel sub signatures from a reference signature, wherein the sub pixel sub signatures correspond to fractional pixel (sub pixel) positions. A target sub signature is compared to each of the sub pixel sub signatures to determine the relative placement of a target object to within a fraction of a pixel.
