EDGE LINKING BY USING CAUSAL NEIGHBORHOOD WINDOW

A novel edge linking algorithm will be presented in this paper. We shall make use of two concepts: (a) the concept of horizontal edge element and (b) the concept of causal neighborhood window for realizing the edge linking. On the basis of these two concepts, the proposed algorithm will carry out (in one pass on the edge map) the edge linking by performing two operations which are the contour chain creation and the contour chain extension. For the illustration of the applicability of our algorithm, some experimental results with real images will be shown.
