基于线性对称的三维边界方向检测

Linear Symmetry Based 3D Edge Orientation Detection

本文提出了一种基于线性对称性检测的三维图象边界方向检测方法，通过引入一种“三元数”的概念，并用它来表示三维空间矢量，使得三维边界方向检测简便易行，文中给出了三维边界方向检测的基本原理和具体算法。

A linear symmetry based 3D edge orientation estimation method is presented.By introducing a“triple number”concept,which can be used to represent 3D space vector,the 3D edge orientation can be easily estimated.The basic principle and the algorithm are described.
