Abstract

Imaging bar-code scanners may use an edge-detection algorithm as the first step to locate a bar code in the image it acquires. This is also likely a step that consumes a significant amount of the total bar-code detection time. A simple but efficient special-purpose edge-detection algorithm is introduced that makes use of the special properties expected from a bar-code image.
