An uncouple Bregman iteration for tomography reconstruction using total variation regularization
总变差正则化断层图像重建的解耦Bregman迭代算法

Recently,there are many practical applications of tomographic reconstruction that consist of minimizing the sum of a residual energy and image total variation(TV).In this paper,we develop an uncoupled iterative algorithm for solving the recent popular TV-regularized CT optimization problem.Using surrogate function,we split the sum minimization scheme to the minimizing weighted least square function and TV denoising with weighted norm iteratively.In order to find the stable solution of this model,we use Cham...
