Résumé
A sampling theorem on the sphere has been developed
recently, requiring half as many samples as alternative
equiangular sampling theorems on the sphere. A reduction
by a factor of two in the number of samples required to
represent a band-limited signal on the sphere exactly has
important implications for compressed sensing, both in
terms of the dimensionality and sparsity of signals. We
illustrate the impact of this property with an inpainting
problem on the sphere, where we show the superior
reconstruction performance when adopting the new sampling
theorem compared to the alternative.
