一种偏微分方程图像平滑方法

A Partial Differential Equations Smoothing Method

在各向异性扩散图像平滑的过程中,保持图像平滑性及保留图像特征都很重要。本文将复域内的扩散过程 与实数域内的扩散过程结合起来,使扩散过程具有更好的平滑效果,并能更好保持图像边缘,用实验证明该方法的有效性。

In the course of noise removal by means of anisotropic diffusion method, it is important to keep image smoothing and to preserve image feature. In this paper , anisotropic diffusion in real field and anisotropic diffusion in complex field are combined .Therefore ,better smoothing is obtained and image edge is preserved well. Experiment result show that this method is valid.
