Abstract
A method involves capturing visual indicia as a digital image, isolating the visual indicia on the digital image, converting the visual indicia to image primitives, identifying and presenting the visual indicia. An apparatus contains a camera for capturing a visual image, a video-to-digital converter, and a computer with a processor, appropriate memory, and software.
