A Unified Plug-and-Play Algorithm with Projected Landweber Operator for Split Convex Feasibility Problems
Shuchang Zhang, Hongxia Wang
In recent years Plug-and-Play (PnP) methods have achieved state-of-the-art performance in inverse imaging problems by replacing proximal operators with denoisers. Based on the prox…
