A nonlinear partial differential equation model based on nonlocal information was proposed to remove noise and preserve the edges. 摘要针对传统扩散模型中的边界模糊问题,提出一种基于非局部信息的非线性偏微分方程去噪模型。
A multi-kernel nonlinear diffusion model for image denoising based on image decomposition was studied, which got the major signal and the minutiae through different models. 摘要研究了一种基于图像分解的多核非线性扩散去噪方法,利用两个非线性扩散模型分别提取图像的主信号和细节信息。
