A Second–Order TV–Based Coupling Model and an ADMM Algorithm for MR Image Reconstruction
Motivated by ideas from two-step models and combining second-order TV regularization in the LLT model, we propose a coupling model for MR image reconstruction. By applying the variables splitting technique, the split Bregman iterative scheme, and the alternating minimization method twice, we can div...
