ABSTRACT:
A method and apparatus for characterizing the performance of either a printer used to print a two-dimensional symbol or an imaging system used to generate an gray-scale image of the printed symbol. After the image is generated, an acquisition target of the symbol is located. The quality of the acquisition target is characterized by thresholding the gray-scale image, run-length encoding the resulting binary image, and computing the correlation coefficient between the run-length-encoded image and a run-length-encoded representation of a defined acquisition target.
