Universal inversion formulas for recovering a function from spherical means
Markus Haltmeier
The problem of reconstruction a function from spherical means is at the heart of several modern imaging modalities and other applications. In this paper we derive universal back-pr…

Inversion of circular means and the wave equation on convex planar domains
Markus Haltmeier
We study the problem of recovering the initial data of the two dimensional wave equation from values of its solution on the boundary $\partial \Om$ of a smooth convex bounded domai…

Extreme Value Analysis of Empirical Frame Coefficients and Implications for Denoising by Soft-Thresholding
Markus Haltmeier, Axel Munk
Denoising by frame thresholding is one of the most basic and efficient methods for recovering a discrete signal or image from data that are corrupted by additive Gaussian white noi…
