Convex hull reconstruction
WebNov 9, 2014 · Each point of the convex hull is the centre of gravity of a mass concentrated at not more than $n+1$ points (Carathéodory's theorem). The closure of the convex hull is called the closed convex hull. It is the intersection of all closed half-spaces containing $M$ or is identical with $E^n$. WebUnlike voxel based visual hull reconstruction where the shape of voxel remains fixed, the shape of convex bricks can adapt to the given silhouettes, thereby reducing the number …

The convex hull is commonly known as the minimum convex polygon in ethology, the study of animal behavior, where it is a classic, though perhaps simplistic, approach in estimating an animal's home range based on points where the animal has been observed. See more In geometry, the convex hull or convex envelope or convex closure of a shape is the smallest convex set that contains it. The convex hull may be defined either as the intersection of all convex sets containing a given subset of a See more Closed and open hulls The closed convex hull of a set is the closure of the convex hull, and the open convex hull is the interior (or in some sources the See more In computational geometry, a number of algorithms are known for computing the convex hull for a finite set of points and for other geometric objects. Computing the convex hull means constructing an unambiguous, efficient representation of the required convex … See more Convex hulls have wide applications in many fields. Within mathematics, convex hulls are used to study polynomials, matrix eigenvalues, and unitary elements, and several theorems in discrete geometry involve convex hulls.
