Abstract(in English) | We introduce the curvature indices of the boundary of a discrete object,and using this indices of points,we define the vertex angles of discrete surfaces as an extension of the chain codes of digital curves.Next,we prove the relation between the number of points indices of which are same and the numbers of holes,genus,and cavities of an object.This is the angular Euler characteristic of a discrete object.Finally,we develop an algorithm for the computation of these characteristics of discrete object. |
