| Abstract: | Practical algorithms for circumscribed circle, circumscribed rectangle set and approximate ratio of long-axis and short- axis of packing parts are presented. They are applied in coding of packing parts to increase the speed of searching needed parts and they are also used as the characteristics of clustering and classing packing parts. Two examples are illustrated at the end of this paper. |
