Fast and accurate edge-based segmentation with no contour smoothing in 2-D real images
Giancarlo Iannizzotto, Lorenzo Vita · IEEE Transactions on Image Processing · 2000
In this paper we propose an edge-based segmentation algorithm built on a new type of active contour which is fast, has a low computational complexity and does not introduce unwanted smoothing on the retrieved contours. The contours are always returned as closed chains of points, resulting in a very useful base for subsequent shape representation techniques.
