This repository contains several scipts that compare the solution of different imaging minimisation problems using the Core Imaging Library (CIL) and cvxpy. All the cvxpy scripts are initially implemented in Matlab for [1] and [2].
- Total Variation Denoising
- Total Generalised Variation Denoising
- Directional Total Variation Denoising
- Total Variation Tomography Reconstruction
- For the cvxpy implementation, the Splitting Conic Solver (SCS) is used by default. Another option is to use the MOSEK solver but it requires a licence. Institutional Academic License is free.
