| 摘 要： | 介绍了基于偏微分方程(PDE)的两种去噪模型,即ROF模型和LLT模型。根据对这两种模型的比较,提出了应用权函数来合并ROF模型和LLT模型的综合模型。实验表明,综合模型既能克服ROF模型和LLT模型的缺点,又能融合它们的优点,在去噪、保护平滑区域、保护边缘和纹理细节方面都有较好的表现。

| Abstract: | The paper introduces two kinds of model for denoising based on partial differential equations,called the ROF model and the LLT model.According to the comparison of the two models,this paper proposes a combined model which combines ROF model and LLT model by weight function.The experiment shows that the combined model not only can overcome the shortcomings of ROF model and LLT model,but also can integrate their advantages.It has better performance in denoising,protecting smoothing region,protecting the edge and texture details. |

| Keywords: | image denoising partial differential equation ROF model LLT model combined model |
