Efficient primal-dual algorithm for imaging applications with matrix stacking, applied to DBT image reconstruction
Emil Y. Sidky, John Paul Phillips, Zheng Zhang +3
The primal-dual hybrid gradient (PDHG) algorithm for solving convex optimization problems that arise in tomographic imaging is revisited. In particular, simplification of the selec…
