摘要：In this paper, we state a new way for measuring symmetry of three-dimensional graphic object. The idea is based on the representation of three-dimensional objects by their Extended Gaussian Image (EGI). The EGI is constructed by mapping each surface normal of any object to the Gaussian sphere. The Gaussian sphere is presented by icosahedrons and 60 rotations are applied. An experimental evaluation demonstrates the satisfactory performance of our approach on a fifty three-dimensional models database.
