G. Iannizzotto et L. Vita, Fast and accurate edge-based segmentation with no contour smoothing in 2-Dreal images, IEEE IM PR, 9(7), 2000, pp. 1232-1237
In this paper we propose an edge-based segmentation algorithm built on a ne
w type of active contour which is fast, has a low computational complexity
and does not introduce unwanted smoothing on the retrieved contours. The co
ntours are always returned as closed chains of points, resulting in a very
useful base for subsequent shape representation techniques.
