摘要
在用各向异性扩散的方法对图像去处噪声的过程中,有时要预先对图像进行平滑处理,再进行各向异性扩散,本文提出了一种对图像预先平滑的方法,并用实验验证了该方法的有效性。
In the course of noise removal by means of anisotropic diffusion method, sometimes image needs to be smoothed beforehand, and then processed by means of anisotropic diffusion method. In this paper, one kind of pre-smoothing method is proposed. Simulation result verifies the effectiveness of the proposed noise removal method.
