Iterative total-variation reconstruction versus weighted filtered-backprojection reconstruction with edge-preserving filtering
Iterative image reconstruction with the total-variation (TV) constraint has become an active research area in recent years, especially in x-ray CT and MRI. Based on Green’s one-step-late algorithm, this paper develops a transmission noise weighted iterative algorithm with a TV prior. This paper comp...
