A parent class for all iterative tomographic reconstruction algorithms
Parameters: |

---|
Backproject d_sino to d_slice
Project d_slice to d_sino
A class for the SIRT algorithm
Parameters: |
|
---|
Warning
This is a beta version of the SIRT algorithm. Reconstruction fails for at least on CPU (Xeon E3-1245 v5) using the AMD opencl implementation.
Create a diagonal preconditioner for the projection and backprojection operator. Each term of the diagonal is the sum of the projector/backprojector along rows [1], i.e the projection/backprojection of an array of ones.
Run n_it iterations of the SIRT algorithm.
A class for reconstruction with Total Variation regularization using the Chambolle-Pock TV reconstruction algorithm.
Parameters: |

Warning
This is a beta version of the Chambolle-Pock TV algorithm. Reconstruction fails for at least on CPU (Xeon E3-1245 v5) using the AMD opencl implementation.
Create a diagonal preconditioner for the projection and backprojection operator. Each term of the diagonal is the sum of the projector/backprojector along rows [2], i.e the projection/backprojection of an array of ones.
Run n_it iterations of the TV-regularized reconstruction, with the regularization parameter Lambda.
