***********************************************************************
1). Get Started:
Run Demo_SIAMFastTV.m.
***********************************************************************
2). FastTVMMS is a Matlab code of the paper:
Y. Huang, M. Ng and Y. Wen,
A Fast Total Variation Minimization Method for Image Restoration,
SIAM Multiscale Modeling and Simulation, Vol.7(2), pp:774-795, 2008.
***********************************************************************
3). Usage:
%% [f,u] = ImDeblurSplit(H, g, param)
% Splitting and Regularization method applied to LS-TV problem
% Image Model: g = H * f + noise
% Algorithm: min_{f,u} = beta/2||H*f-g||_2^2 + 1/2||f-u||_2^2 + lambda*TV(f) ...(1)
% Inputs:
% H: blur matrix (generated by point spread function)
% g: observed image
% param:a structure containing algorithm parameters
% param.TVWeight: lambda in (1) (default: 2)
% param.FitWeight: beta in (1) (default: 1e1)
% param.Tol: stopping criterion (default: 1e-4)
% param.MaxIter: stopping criterion for max iteration for out iteration
% param.TVIter: max iteration number for inner iteration
% Outputs: f, u in (1).
