More Information
Summary:Estimation approach of similarity of convex polyhedron is described. Convex polyhedron is represented by distance from center of gravity to face and the angle. Similarity is established with the following element.: (a) Fourie descripter calculated by 2 dimensions FFT which is provided from curved surface after coordinate transformation. (b) Correlation coefficient of curved surface provided after coordinate transformation. And similarity was calculated with some data made with computer. As a result, similarity estimation of convex polyhedron was explained by this element. And the resembled part was shown.
