摘要:

本文基于Perona-Malik模型和四阶偏微分方程提出了耦合偏微分方程的平滑方法。实验表明,该方法能很好兼顾图像噪声消除和边缘保持,避免了二阶偏微分方程处理图像常出现的块效应,使图像平滑自然。

关键词: 图像去噪 各向异性扩散 四阶偏微分方程

Abstract:

A coupled PDE method for image denoising is proposed based on the Perona-Malik model and the fourth order PDE, The experiments show it is able to remove noises while preserving edges well and avoiding the block effect which is easily seen in the images processed by the second order PDE.

Key words: (image denoising, anisotropic diffusion, fourth order PDE)
