Limited-angle CT Reconstruction with ep Regularization

Limited-angle reconstruction is a very important but challenging problem in the field of computed tomography (CT) and it has been extensively studied for many years. However, some difficulties still remain. Based on the theory of visible and invisible boundary developed by Quinto et.al, we propose a reconstruction model for limited-angle CT, which encodes the visible edges as priors to recover the invisible ones. The new model introduces an anisotropic ep (0
