Sliced Optimal Transport on the Sphere
Michael Quellmalz, Robert Beinert, Gabriele Steidl
Sliced optimal transport reduces optimal transport on multi-dimensional domains to transport on the line. More precisely, sliced optimal transport is the concatenation of the well-…
A Frame Decomposition of the Funk-Radon Transform
Michael Quellmalz, Lukas Weissinger, Simon Hubmer +1
The Funk-Radon transform assigns to a function defined on the unit sphere its integrals along all great circles of the sphere. In this paper, we consider a frame decomposition of t…
A double Fourier sphere method for -dimensional manifolds
Sophie Mildenberger, Michael Quellmalz
The double Fourier sphere (DFS) method uses a clever trick to transform a function defined on the unit sphere to the torus and subsequently approximate it by a Fourier series, whic…
