| 摘 要： | 提出一种基于各向异性扩散的图像降噪新方法.该方法能够避免Perona和Malik以及You和Kaveh等人提出的方法中对参数选择的困难， 而且也能够克服Catte方案对图像进行预平滑的过程中所面临的问题.实验结果表明，该方法在图像增强过程中的降噪和细节保留方面都能有较好的效果.

| Abstract: | In this paper, we discuss deficiency of the Perona Malik scheme and some other schemes derived from it, and propose a new operator. The proposed method can avoid difficulties in choosing parameters encountered in Perona-Malik and You-Kaveh schemes, and overcome the pre-smoothing problems in the Catte scheme. Experimental results show that the new scheme can achieve good results in noise removal and detail preservation in image smoothing. |
