Total Variation Minimization in Compressed Sensing
Felix Krahmer, Christian Kruschel, Michael Sandbichler
This chapter gives an overview over recovery guarantees for total variation minimization in compressed sensing for different measurement scenarios. In addition to summarizing the r…
Testable uniqueness conditions for empirical assessment of undersampling levels in total variation-regularized x-ray CT
Jakob S. Jørgensen, Christian Kruschel, Dirk A. Lorenz
We study recoverability in fan-beam computed tomography (CT) with sparsity and total variation priors: how many underdetermined linear measurements suffice for recovering images of…
Computing and Analyzing Recoverable Supports for Sparse Reconstruction
Christian Kruschel, Dirk A. Lorenz
Designing computational experiments involving minimization with linear constraints in a finite-dimensional, real-valued space for receiving a sparse solution with a precis…
