hullbased
Hullbased is an expression used in mathematics, computer science, and related fields to describe approaches that rely on the convex hull of a set of points, or more generally on a hull that encloses a geometric object. The convex hull of a finite point set is the smallest convex set that contains all the points; many hullbased methods use this boundary as a geometric primitive for analysis, recognition, or planning.
In computational geometry, hullbased algorithms focus on computing or manipulating convex hulls; classic algorithms include the
In computer vision and graphics, hullbased shapes use the convex hull as a coarse representation of object
Limitations include the inability to capture concavities precisely, high computational cost in high dimensions, and distortion
