Image denoising via a new anisotropic total-variation-based model

作者：

Highlights：

• This paper proposed a new anisotropic total variation model.

• The anisotropic is based on the couple between the local weighted operator and the gradient operator.

• The proposed model can be efficiently solved via the alternating direction method of multipliers.

• Numerical comparisons showed the effectiveness of the proposed model.
