Convex hull in matlab
WebMay 6, 2024 · All of the codes in that toolbox generally first took the convex hull of the data. Anything inside the convex hull is meaningfless in terms of a bounding polygon anyway. It dramatically reduces the problem, since it needs only to work with the edges of … WebReturns information about the smallest convex complex of a set of input points in N -dimensional space (the convex hull of the points). By default, indices to points forming the facets of the hull are returned; optionally normals to the facets and the generalised surface area and volume can be returned. This function interfaces the Qhull library.
