A Fast Interior Point Method for Atomic Norm Soft Thresholding
Thomas Lundgaard Hansen, Tobias Lindstrøm Jensen
The atomic norm provides a generalization of the -norm to continuous parameter spaces. When applied as a sparse regularizer for line spectral estimation the solution can be…
Accelerated gradient methods for total-variation-based CT image reconstruction
Jakob Heide Jørgensen, Tobias Lindstrøm Jensen, Per Christian Hansen +3
Total-variation (TV)-based Computed Tomography (CT) image reconstruction has shown experimentally to be capable of producing accurate reconstructions from sparse-view data. In part…
Implementation of an Optimal First-Order Method for Strongly Convex Total Variation Regularization
Tobias Lindstrøm Jensen, Jakob Heide Jørgensen, Per Christian Hansen +1
We present a practical implementation of an optimal first-order method, due to Nesterov, for large-scale total variation regularization in tomographic reconstruction, image deblurr…
