Anatomical priors
Anatomical priors in TIGRE.
This is work in progress, making a PR for visibility.
Tasks before merge
- [X] PICCS
- [ ] Multi-GPU source
- [ ] Add PICCS algorithm to python
- [ ] Directional TV (CUDA). Gradient-based like standard TV minimizer? or proximal based like ROF? both?
- [ ] Test the regularized within a minimization algorithm. ASD-POCS.
- [ ] Matthias Ehrhardt's Directional TV. The other one I was thinking about was a TV that is an ellipsoid shape, that changes its angle w.r.t. an anatomical prior image. Ehrhardt's directional TV changes in value w.r.t. an underlying anatomical prior (I think).
- [ ] Add educational demos. This is called anatomical priors but of course also works for industrial tomography.
