Super-Resolution on the Two-Dimensional Unit Sphere
Frank Filbir, Kristof Schröder, Anna Veselovska
We study the problem of recovering an atomic measure on the unit 2-sphere given finitely many moments with respect to spherical harmonics. The analysis relies on the…

Exact Recovery of Discrete Measures from Wigner D-Moments
F. Filbir, K. Schröder
In this paper, we show the possibility of recovering a sum of Dirac measures on the rotation group from its low degree moments with respect to Wigner D-functions only. The…
