A Framework for Directional and Higher-Order Reconstruction in Photoacoustic Tomography
Yoeri E. Boink, Marinus J. Lagerwerf, Wiendelt Steenbergen +3
Photoacoustic tomography is a hybrid imaging technique that combines high optical tissue contrast with high ultrasound resolution. Direct reconstruction methods such as filtered ba…
Combining Contrast Invariant L1 Data Fidelities with Nonlinear Spectral Image Decomposition
Leonie Zeune, Stephan A. van Gils, Leon W. M. M. Terstappen +1
This paper focuses on multi-scale approaches for variational methods and corresponding gradient flows. Recently, for convex regularization functionals such as total variation, new…
Risk Estimators for Choosing Regularization Parameters in Ill-Posed Problems - Properties and Limitations
Felix Lucka, Katharina Proksch, Christoph Brune +4
This paper discusses the properties of certain risk estimators recently proposed to choose regularization parameters in ill-posed problems. A simple approach is Stein's unbiased ri…
