Abstract

We introduce a new formulation for total variation minimisation in image denoising. We also present a linearly convergent first-order method for solving this reformulated problem and show that it possesses a nearly dimension-independent iteration complexity bound.

图像处理中总变差最小化的一阶线性收敛算法。

介绍了一种新的图像去噪中总变差最小化的公式。我们还给出了一个线性收敛的一阶方法来求解这个重表述问题，并证明了它具有一个几乎与维无关的迭代复杂度界。
