曲率驱动与边缘停止相结合的非线性扩散及其在图像去噪中的应用

Image Filtering by Combination of the Curvature-Driven and Edge-Stopping Nonlinear Diffusion

根据等照度线曲率在图像表征中的重要意义,将曲率作为一个控制传导率的因素引入非线性扩散方程,提出了一个新的曲率驱动与边缘停止相结合的非线性扩散模型,实验结果表明这一模型在图像去噪方面较经典的P-M方程具有更好的性能.

Based on the consideration of importance of isophoto curvatures for image representation, curvature, as a new control factor into the nonlinear diffusion equation to build a novel diffusion model, was introduced,which combines the Curvature-driven with Edge-stopping （C＆E）. The experimental results show that it performs better than the Perona ＆ Malik Model for image filtering.
