| 摘要: |
| 平均曲率运动模型(MCM)是基于偏微分方程的图像处理模型的一种，具有明确的几何意义。提出了模型中退化扩散项的精确计算方法，并采用了两种新的方向估计方法。实验证明了新方法所得的结果优于原方法。 |

| Abstract: |
| One of the most important model in image processing based on partial difference equations is the mean curvature motion model, which has a geometric property. An accurate calculation method to the degenerating diffusion term in this model is proposed, adopting two new orientation estimation methods-one based on the Hessian matrix and one based on tensor-and then making a comparison between the two. The results of the experiments prove that these measurements are effective. |
