Description
Summary:In this paper, a novel 3D orthogonal polynomial moment based on 3D U system polynomials is proposed, and is used for 3D model retrieval. U system is a kind of complete and orthogonal polynomials system. In this paper, we combine U system with spherical harmonic functions and define a shape descriptor-Usystem rotation invariant moments. The performance of the proposed method is evaluated by constructing precision/recall diagrams. Results clearly demonstrate effectiveness of this new method in the 3D-model retrieval process and superiority over the traditional Zernike moment invariants.
