Abstract
This paper proposes a novel approach to calculate polyhedra moments. A t first the Gaussian theorem is used to convert a volume integral into a surface one, by which we decrease the moment computational complexi ty from O(N3) to O(N2). Then, an iterative method is proposed to calcu late the surface integral. Finally, some comparison shows that the com putational complexity of the new method is independent of voxel number s of polyhedra, therefore the new moment computation is more efficient .
