Study of Contour Detection for Growing Neural Gas based 3D Shape Recognition

Abstract

This paper presents the algorithm of extracting contour nodes with the use of self-organising networks, which is called Growing Neural Gas (GNG). The system imitates how to get the contour nodes in binary image. And, this algorithm also includes getting contour nodes with angle information for dealing with GNG. Therefore, algorithm consists of their two methods. The proposed method can get the contour nodes exactly compared with advance literature.
