|Abstract:||A fast algorithm for computing the convex hull of a set of distinct points or an arbitrarily shaped object in the Cartesian discrete plane is presented in this paper. A sequence of points is first extracted from the input image. These points form a non-self-intersecting polygon. Then, a cross-product rule is used to check the convexity of the polygon and compute the convex hull from it. © 1995.|
