New 3D Fourier Descriptors for Genus-Zero Mesh Objects
The 2D Fourier Descriptor is an elegant and powerful technique for 2D shape analysis. This paper intends to extend such technique to 3D. Though conceptually natural, such an extension is not trivial in that two critical problems, the spherical parametrization and invariants construction, must be solved. By using a newly developed surface parametrization method-the discrete conformal mapping (DCM) - we propose a 3D Fourier Descriptor (3D-FD) for representing and recognizing arbitrarily-complex...[Show more]
