This paper proposes a fast and high-definition contour-tracing algorithm for digitized binary images. Only the coordinates of white-to-black and black-to-white transition points on each scan line are used as data for the contour tracing. The resulting description of the contour is the combined set of ten newly developed run-type direction codes. The code is determined automatically by an automaton while the horizontal coordinates of two transition points in the two adjacent scan lines are… CONTINUE READING
