WebApr 12, 2024 · We consider the convergence rate of the alternating projection method for the nontransversal intersection of a semialgebraic set and a linear subspace. For such an intersection, the convergence rate is known as sublinear in the worst case. We study the exact convergence rate for a given semialgebraic set and an initial point, and investigate … WebAug 12, 2024 · Total generalized variation (TGV) is a second-order gradient minimization proposed by Kunisch. et al. [ 21 ]. It incorporates more adjacent elements than TV and regards the second-order gradient of images as the sparse coefficients, as Fig 2B illustrates.
