Abstract

This paper presents 3D shape modeling using surface parameterization by spherical harmonics and the combination of superquadric and spherical harmonics . Although, the results obtained with the two representation schemes are comparable, we opt for the spherical harmonics model. Our approach is divided into two parts. The first consists in extracting set of 3D points which corresponds to epicardium and endocardium wall respectively. For this purpose, we have segmented the original SPECT myocardium data. The second part consists in fitting the surface on this set of unstructured 3D points using the both methods: a parametric surface description using (SH) and a combination of two models (SQ-SH).
