Fast spherical Bessel transform via fast Fourier transform and recurrence formula
We propose a new method for the numerical evaluation of the spherical Bessel transform. A formula is derived for the transform by using an integral representation of the spherical...

Surface Alignment of 3D Spherical Harmonic Models: Application to Cardiac MRI Analysis
The spherical harmonic (SPHARM) description is a powerful surface modeling technique that can model arbitrarily shaped but simply connected 3D objects and has been used in many app...

Robust Mapping of Brain Surface Meshes onto a Unit Sphere
Complex shapes - such as the surface of the human brain may be represented and analyzed in frequency space by a spherical harmonics transformation. A key step of the processing ch...

3D Model Retrieval with Spherical Harmonics and Moments
We consider 3D object retrieval in which a polygonal mesh serves as a query and similar objects are retrieved from a collection of 3D objects. Algorithms proceed first by a normal...
