摘      要：The authors introduce a method to reconstruct shape deformations of objects using linear interpolation of spherical harmonic (SH) representation parameters. It is shown that uniform shape deformation results in fairly linear changes in SH parameters. Therefore, shape changes can be reconstructed once the characteristics of the deformation are obtained in the SH domain.
