An Optimal-Dimensionality Sampling for Spin- Functions on the Sphere
Usama Elahi, Zubair Khalid, Rodney A. Kennedy +1
For the representation of spin- band-limited functions on the sphere, we propose a sampling scheme with optimal number of samples equal to the number of degrees of freedom of th…

Iterative Residual Fitting for Spherical Harmonic Transform of Band-Limited Signals on the Sphere: Generalization and Analysis
Usama Elahi, Zubair Khalid, Rodney A. Kennedy +1
We present the generalized iterative residual fitting (IRF) for the computation of the spherical harmonic transform (SHT) of band-limited signals on the sphere. The proposed method…
