An inexact primal–dual method with correction step for a saddle point problem in image debluring

In this paper, we present an inexact primal–dual method with correction step for a saddle point problem by introducing the notations of inexact extended proximal operators with symmetric positive definite matrix D . Relaxing requirement on primal–dual step sizes, we prove the convergence of the prop...
