Abstract

In general, in order to recognize and modelling the 3-D object, it is necessary to have the method to express the shape of 3-D object. In case of 2-D like silhouette image, the extraction of vertex on the boundary of the object can be obtained by using 2-D curvature function. But, in case of 3-D, because 3-D curvature function that can calculate the surface curvature values of 3-D object doesn''t exist, it is difficult to express the shape of 3-D object. Therefore, in this paper, a new method is presented. With this presented method, the approximated surface curvature values and vertex of 3-D object can be obtained effectively using the principle of 2-D curvature and the least square method.
