Compared with traditional DEM or TIN based methods, this pure vector approach obtains not only the topological structure of drainage system in planar graph, but also the valley distribution polygon range. Depending on geometrical computation and judgment of vector line, polygon, the structured properties in drainage representation is enhanced, avoiding the case of noise disturbance in DEM based method. The core algorithm makes use of the ability of Delaunay triangulation in detecting hierarchical structure of each contour line.

中文摘要：基于Delaunay三角网模型在矢量等高线基础上通过弯曲特征分析，给出了一种地形结构特征提取及谷地树组织的方法，与传统的基于DEM或TIN数据结构提取地形特征的方法相比，该方法不仅得到了谷地系统在平面图上的拓扑结构，还获得了河谷在空间分布上的汇水范围，依托矢量线、多边形的几何关系判断，增强了谷地树组织中的结构化，避免了DEM方法中的噪音干扰，方法的核心是Delaunay三角网在单根等高线弯曲深度表达上的层次结构识别。

Under the assumption that the locations of two inner corners of eyes and two outer corners of mouths are known, in the new method, the approximate area for the two eyes is found first, and then the state of eyes in this area is determined by using the eyes local templates and the Hausdorff distance. Similarly, the state of the mouth can also be known. Finally the whole face contour is searched by global template corresponding to the estimated eyes and mouth states.

在给定眼睛两个内眼角和嘴巴两个外嘴角的前提下，新方法首先用全局模板粗略确定眼睛所在区域，然后在此区域用眼睛的两个局部模板以及Hausdorff距离判断眼睛状态，同理可检测嘴巴状态，最后调用相应的全局模板去搜索整脸轮廓。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
