On the shape of a set of points in the plane
WebA shape or figure is a graphical representation of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture, or material type. A plane shape or plane figure is constrained to lie on a plane, in contrast to solid 3D shapes. A two-dimensional shape or two-dimensional figure (also: 2D shape or 2D figure) may … http://www.cs.uu.nl/research/techreps/repo/CS-2011/2011-017.pdf

WebA generalization of the convex hull of a finite set of points in the plane is introduced and analyzed. This generalization leads to a family of straight-line graphs, called ``shapes'''', which seem to capture the intuitive notion of ``fine shape'''' and ``crude shape'''' of point sets. .br Additionally, close relationships with Delaunay ... WebAbstract: Let S be a set of n points in the Euclidean plane. The convex layers of S are the convex polygons obtained by iterating on the following procedure: compute the convex hull of S and remove its vertices from S.This process of peeling a planar point set is central in the study of robust estimators in statistics. It also provides valuable information on the …
