RED-PSM: Regularization by Denoising of Factorized Low Rank Models for Dynamic Imaging

arXiv:2304.03483v4 Announce Type: replace-cross
Abstract: Dynamic imaging addresses the recovery of a time-varying 2D or 3D object at each time instant using its undersampled measurements. In particular, in the case of dynamic tomography, only a single projection at a single view angle may be available at a time, making the problem severely ill-posed. We propose an approach, RED-PSM, which combines for the first time two powerful techniques to address this challenging imaging problem. The first, are non-parametric factorized low rank …
