Convergence Analysis of Primal-Dual Based Methods for Total Variation Minimization with Finite Element Approximation
We consider the total variation minimization model with consistent finite element discretization. It has been shown in the literature that this model can be reformulated as a saddle-point problem and be efficiently solved by the primal-dual method. The convergence for this application of the primal-dual method has also been analyzed. In this paper, we focus … Read more
