Variational regularization of complex deautoconvolution and phase retrieval in ultrashort laser pulse characterization
Stephan W. Anzengruber, Steven Buerger, Bernd Hofmann +1
The SD-SPIDER method for the characterization of ultrashort laser pulses requires the solution of a nonlinear integral equation of autoconvolution type with a device-based kernel f…
A global minimization algorithm for Tikhonov functionals with sparsity constraints
Wei Wang, Stephan W. Anzengruber, Ronny Ramlau +1
In this paper we present a globally convergent algorithm for the computation of a minimizer of the Tikhonov functional with sparsity promoting penalty term for nonlinear forward op…
On the interplay of basis smoothness and specific range conditions occurring in sparsity regularization
Stephan W. Anzengruber, Bernd Hofmann, Ronny Ramlau
The convergence rates results in -regularization when the sparsity assumption is narrowly missed, presented by Burger et al. (2013 Inverse Problems 29 025013), are based on…
