Image denoising algorithm of compressed sensing based on alternating direction method of multipliers

In this paper,we propose an image denoising algorithm for compressed sensing based on alternating direction method of multipliers(ADMM).We prove that the objective func-tion of the iterates approaches the optimal value.We also prove the O(1/N)convergence rate of our algorithm in the ergodic sense.At the same time,simulation results show that our algorithm is more efficient in image denoising compared with existing methods.
