基于PDE的图像降噪方法

Image denoising methods based on PDE

回顾了3种传统的PDE图像降噪方法,即φ函数、基于散度的PDE和基于拉普拉斯算子的扩散PDE;指出了可将扩散方程与自由薛定锷方程结合,形成新的基于复扩散的图像降噪处理方法。

This paper reviewed three image denoising methods based on PDE such as φ - function, divergence- based PDE and diffusion PDE based on oriented Laplacian operator,and points out that new image denoising method based on complex diffusion can be formed by combining the diffusion equation with free Schrodinger equation.
