In this paper, we modify the second accelerated proximal gradient (APG) method proposed by Nesterov in [12] (and named by Tseng in [13] ) for solving the total variation (TV) image deblurring problems. We also use the variables in [1] to decouple the problems so that we need not to solve the correlative subproblems in each iteration, borrow the idea of [19] to replace the Lipschitz constant by an appropriate positive-definite matrix, and use the continuation technique in [15] to provide good initial solutions for our algorithm.
