Investigation and implementation of:

• Baranov minimal projections criteria
• Gerchberg-type initialisation (few-angles recovery)
• Miltigrid reconstruction (recovery on lower scale, upsampling)
• ?

Implement the capability of FBP - reconstruction with vector given geometry. Implementation of a filter applied to backprojection.

Add Student's t data fidelity

• Add Group-Huber data fidelity

Automated plugin to crop 2D and 3D projection data (X-Z cropping) in order to reduce the data size before passing it to iterative reconstruction.

Hi, is it possible to release a Python3.6 build on Win64? As astra-toolbox only supports up to python 3.6. Thanks.

how to run this software with multi-GPU?

to add ADMM algorithm with inner CGLS solver

Is it possible to construct 3d point cloud from sinogram images...

Incorrectly set tolerance can trigger the premature stop of the algorithm. It makes sense to do the n-number of iterations despite the tolerance condition. Hence tolerance condition must be checked after some hardcoded number of iterations, e.g. 10 for OS methods and 200 for non-OS.

FISTA - Ordered Subsets

stripe-weighted least-squares (SWLS) model as presented in

I think this line always evaluates to True as a string cannot be LS and PWLS at the same time.

consider rewriting as

if datafidelity not in ['LS','PWLS']:
    raise ValueError()
