%X An alternating minimization method for the reconstruction of MR images with wavelet sparsity,including the convergence analysis of this algorithm,is presented in this paper.Our algorithm is base on a half-quadratic penalty method.The optimization problem with wavelet sparsity is splited into two sub-problems:the X-subproblem and the Y-subproblem.The solution for the original problem can be obtained by alternately solving the two subproblems,in which the Y-subproblem is solved via a 1D soft-thresholding or s...
