变正则参数方法在带噪图像保边缘恢复中的应用

Adaptive Regularization Parameter Approach for Noisy Image Restoration with Edge Preserving

提出变正则参数的变分方法 该方法通过选取随梯度变化的自适应的正则参数 ,达到去噪和保持边缘的目的 通过 5点格式构造出变分模型的离散解法 。

This paper presents a variational approach using adaptive regularization parameter for keeping the information of edges and denoising largely. Through constructing a 5-points scheme of the partial differential equation (PDE), a numerical solution can be designed to avoid the complicated computing of Green function.
