abstract = {<p style="text-align: justify;">In this paper, we propose a new projection method for solving a general minimization
problems with two $L^1$-regularization terms for image denoising. It is related
to the split Bregman method, but it avoids solving PDEs in the iteration. We employ
the fast iterative shrinkage-thresholding algorithm (FISTA) to speed up the proposed
method to a convergence rate $O$($k^-$$^2$). We also show the convergence of the algorithms.
Finally, we apply the methods to the anisotropic Lysaker, Lundervold and Tai (LLT)
model and demonstrate their efficiency.</p>},
