Characteristic of Rectangular Vertex Chain Code for Shapes with Hole

Vertex chain code is one of image representation that was introduced by Bribiesca in 1999. Each code in this chain code indicates the number of cell vertices, which are in touch with the bounding contour of the shape in that element position. It is possible to represent shape in triangular, rectangular and hexagonal cells in vertex chain code. A shape that is used in vertex chain code that is proposed by Bribiesca is a shape without hole. This paper will explained vertex chain code in rectangular cell for shape with hole. Some characteristic of rectangular vertex chain code for shape with hole is presented by using some example of shapes.
