In the last part of this dissertation, we discuss how to model an image is discussed and how to segment an image by EDEK.Zero-Cross principle is a classical concept in signal processing. We generalize the concept to be zero normal curvature after the geometry frame built. Furthermore, we present the explanation to choose the dual parameters in SPMVIF. And we research why the Laplacian gradient superior to edge gradient.

梯度方向二阶导数过零原理是信号处理中的经典结论，在运用微分几何的知识建立SPMVIF的几何框架的同时，将这个结论推广到零-法曲率的形式；另外我们对SPMVIF的双参数选取规则进行了讨论并给出它们的几何意义，并且对SPMVIF中法向矢量选取时拉普拉斯梯度优于边缘图像梯度的结论给予统计信息熵的解释。

第二章，我们研究了Ricci益率有一定下界的完备非紧n维Riemann流形，证明了这样的流形在满足一定体积增长条件下微分同胚于n维欧几里德空间。

In order to improve present Monte Carlo methods, method changing the node to optimistical orientation corresponding to the system having the lowest energy was proposed, which ensures the grain boundary moving to its curvature center. The new method avoided re-nucleation, and increased simulation efficiency, and made the simulation process more approaching the physics foundation of grain growth. The results show that the grain growth exponent, n=0.478, is close to its theoretic value, and the topological structure accorded with the normal grain growth of the real material.
