一种基于全变差的新去噪方法

A New Method for Noise Removal Based on Total Variation

提出了一种新的基于全变差的图像去噪方法。该方法通过对梯度变化将各向同性扩散与各向异性扩散有机的结合起来,并考虑图像的局部特征信息。自适应地改变扩散参数,较好地处理了去除噪声、保持边缘角点这对在图像去噪中存在的矛盾。实验结果表明该方法有很好的性能。

This paper presents a new total variational approach using adaptive parameter for denoising and keeping the information of edges and corners. It not only introduces the idea of combining isotropic and anisotropic diffusion, but also considers the local information of the image. Experiment results indicate that it performs well.
