基于偏微分方程的去噪方法

利用偏微分方程抑制图像噪声已经被认为是具有显著效果的图像去噪技术。在阐述图像噪声模型的基础上研究了图像去噪的偏微分方程模型,并对偏微分方程中的参数选择进行了讨论。为了保持图像的边缘信息,对经典模型参数进行了改进。实验结果表明,偏微分方程适用于图像噪声的抑制,并且可以在抑制图像噪声的同时,保持较好的边缘信息。

Denoising Method Based on Partial Differential Equation

Image noise removing by the partial differential equation(PDE) is well known technique for their good processing results.In this paper,based on discussing the model of image noise,we research the model of the PDE,and discuss the parameter of the PDE.For preserving the information of image edge,we modify the parameter of classical model.The experimental results show that the PDE can reduce the image speckle and preserve more edge features.
