Abstract
This paper presents a new edge-detection method which, based on simple arithmetic and logical operations, consists of three procedures: imag e binarisation, image contraction, and image subtraction. Experiments showed that the proposed algorithm could generate a path one pixel wid e with continuous edges, and the proposed algorithm had a better edge- detection accuracy than the 4-connected, 8-connected, and the Sobel te chniques. Therefore, the proposed edge-detection algorithm is feasible for use in automatic visual inspection systems.
