摘要 本文在研究二阶各向异性扩散方程与四阶各向异性扩散方程的基础上,提出了二者结合的组合扩散算子,同时提出了新的扩散系数。实验表明,新方法对高斯噪声比原有的两种方法有更好的去噪效果,不但能够有效地提高峰值信噪比,而且也消除了四阶方程中所出现的"孤立点"。 The second-order and fourth-order anisotropic diffusion equations were analyzed in the paper. A new diffusion operator combining P-M model with YK model was proposed and a new diffusion parameter is used to improve the denoising effects. The nu- merical experiments show that the new method is better than the two above on removing Gaussian noise. It can not only get higher value of PSNR, but also eliminate the isolated speckles in fourth-order equation.
