Optimal-Dimensionality Sampling on the Sphere: Improvements and Variations

Nafees, Wajeeha;Khalid, Zubair;Kennedy, Rodney;McEwen, Jason D.

Description

For the accurate representation and reconstruction of band-limited signals on the sphere, an optimal-dimensionality sampling scheme has been recently proposed which requires the optimal number of samples equal to the number of degrees of freedom of the signal in the spectral (harmonic) domain. The computation of the spherical harmonic transform (SHT) associated with the optimal-dimensionality sampling requires the inversion of a series of linear systems in an iterative manner. The stability of...[Show more]
