[matlab] TVAL3 DL : 0: %TVDENOISE Total variation grayscale and color image denoising % u = TVDENOISE(f,lambda) denoises the input image f. The smaller % the parameter lambda, the stronger the denoising. % % The output u approximately minimizes the Rudin-Osher-Fatemi (ROF) % denoising model % % Min TV(u) + lambda/2 || f - u ||^2_2, % u % % where TV(u) is the total variation of u. If f is a color image (or any % array where size(f,3) > 1), the vectorial TV model is used, % % Min VTV(u) + lambda/2 || f - u ||^2_2. % u % % TVDENOISE(...,Tol) specifies the stopping tolerance (default 1e-2). % % The minimization is solved using Chambolle's method, % A. Chambolle, "An Algorithm for Total Variation Minimization and % Applications," J. Math. Imaging and Vision 20 (1-2): 89-97, 2004. % When f is a color image, the minimization is solved by a generalization % of Chambolle's method, % X. Bresson and T.F. Chan, "Fast Minimization of the Vectorial Total % Variation Norm and Applications to Color Image Processing", UCLA CAM % Report 07-25.

[Special Effects] TVAL3_beta2.4 DL : 0: TVAL3算法是基于增广拉格朗日法和交替方向法的全变分最小化算法。TVAL3算法是在最小全变分法的基础上，结合了增强型拉格朗日函数和交替最小化方法。通过交替最小化方法寻找增强型拉格朗日模型的最小值，再由最速下降法进行迭代，更新拉格朗日乘子。-TVAL3: TV minimization by Augmented Lagrangian and ALternating direction ALgorithms.The TVAL3 algorithm is based on the minimum total variation method, which combines the enhanced Lagrange function and the alternating minimization method. The minimum value of the enhanced Lagrange model is sought by the alternate minimization method, and then the iterative method is updated by the steepest descent method.
