Abstract
A system and method for use in decoding a dot code carried by a glass substrate or container. The method comprises converting an image of a dot code to a grayscale image to remove effects of at least one of color of the glass substrate or color of ambient light, where the image includes a plurality of circular dots; detecting edges of the circular dots in the grayscale image to produce an edge-detected image; filtering the edge-detected image to produce a filtered image; applying a Close transform to convert open instances of the circular dots to closed instances of the circular dots; and identifying quantity and position of all of the circular dots. The method may further include applying a transform to remove background noise from the filtered image and/or filling all the closed instances of the circular dots.
