Geodesic The shortest distance between two points on the surface of an ellipsoid.

最短线的﹚描述一个椭球世界模型表面上两点之间的最短距离。

Similarly, numerical experiments are performed to demonstrate the efficiency and efficacy of the geodesic distance based MFS for piecewise smooth domain. In addition, the effect of the number of collocation points and the stability with respect to the anisotropy are discussed.In Appendix A.

在后面同样给出了数值例子以说明方法的优越性，不同的是这里考察了分片光滑的几何区域，并加上了配置点数目对数值结果的影响以及该方法对各向异性的稳定性分析。

During the simulation, themost important problem is to compute the geodesic distance as fast and exactly as possible. We modify the approximating method and make it work for the concave andmultiple sources.

在这个模拟方法中，使用了改进的近似快速计算三角网格上测地距离的方法，使之能处理凹面及多源点的情况。

The method includes identifying (101) a surface in the image, and for each point in the image, calculating (102) a first curvature measure, forming (103) a set of rings of points about each point, each ring being of equal geodesic distance from a center point for the ring, calculating (104), for each ring, a standard deviation of the first curvature measure, and selecting (105) those rings with a minimum standard deviation for the first curvature measure.

该方法包括在所述图像中识别(101)表面；为该表面中的每个点计算(102)第一曲率量；为该表面中的每个点形成(103)围绕每个点的一组点环，每个环具有到该环的中心点的相等的测地距；为每个环计算(104)第一曲率量的标准偏差；以及选择(105)那些具有第一曲率量的最小标准偏差的环。

First, each shape is represented by the eigenvectors of an appropriately defined affinity matrix based on approximated geodesic distance, forming a spectral embedding which achieves normalization against rigid-body transformations, uniform scaling, and shape articulation (i.e., pose changing). This procedure is called the pose-oblivious transform.

首先，针对每一个形状都基于谱嵌入的方法求得其相应的谱嵌入表示，这里的谱嵌入是基于以近似测地距离为基础构造出的仿射矩阵的特征向量得到的，这一过程称为姿态无关变换，经过这一变换，模型的形状的描述符就具备了刚体变换不变、均匀缩放不变和姿态无关的特性。

The main advantages of EGGLE include:the fixed neighborhood parameter k,only one time for constructing neighborhood graph and geodesic distance matrix,only needing to choose generalized Gaussian functions many times for constructing many Laplacian matrixes,obtaining multiple independent low-dimensional coordinate sets, independently training multiple classifiers,and combining classification results of these component classifiers to produce the final identification.

3提出了一种基于GGLE的集成判别算法，该算法的主要优点是：近邻参数k固定，邻接矩阵和测地线距离矩阵都只构造一次，只需要多次选择广义高斯型函数构造多个拉普拉斯矩阵，获取多个独立的低维空间坐标集合，独立学习分类器，集成分类识别。
