利用一致锐度算子的两个特性，结合小波变换与偏微分方程的方法，提出一个新的图像去噪方法。经仿真实验，表明该方法具有很好的图像去噪效果。

According to the two characteristics of region homogeneity measure， we combine the methods of wavelet transformation and partial differential equation to put forward a new method for image denoising．Experimental results show this method is efficient for image denoising．
