摘要

提出了一种改进的四阶非线性扩散滤波方法。引入了边缘检测函数，该方法可以自适应调节扩散速度。与以往的一些高阶滤波方法相比，该方法在去噪的同时能够保持边缘。实验结果证明了这种四阶非线性扩散方法的有效性。

An improved fourth order nonlinear diffusion method for image denoising

An improved fourth order nonlinear diffusion filtering method is presented. An edge-detection function is introduced and the new method can adjust the diffusion speed adaptively. Compared to some previous high order filtering, the proposed method can preserve edges while denoising. Experimental results demonstrate the performance of the new fourth order nonlinear diffusion method.
