提取信息

Thismethod adopted affine transformation model and a Lie derivative-based analytical algorithm.We introduced the process and characters in extracting information of biological visionsystem, studied the feasibility of the generalized Gabor function used as receptive fieldfunction in extracting information and analyzed affine transformation group and Liederivatives. Finally, we deduced the mathematical denotation for Lie derivatives, i.e. theinfinitesimal generator of the geometric distortion in affine transformation.

对生物视觉信息提取的过程及特点进行了介绍，其中主要研究了广义Gabor函数作为感受野函数提取初级视觉信息的可行性；对仿射变换作为外界图像信息在视觉成像系统上的投影模型的原理进行了初步讨论；对Lie变换群微分算子用于提取仿射变换不变量的分析方法作了剖析，并推导了该方法中关键部分——仿射变换Lie微分算子的具体表达式，也就是几何变形无限小微分算子的计算表达式，使下一步编程实现该方法成为可能。

The water body was extracted by combining density slicing of TM 5 or TM 7 with the terrain mask produced by DEM. NDVI was used to extract vegetation information, and desertification land and salification land information was extracted by the SAM classification method. Confusion matrix shows that the classification precision is 86.2%.

But it is easily noticed that certain activities, such as the maintainance and reengineering of the software, the modernization of the code written before, remain problems unsolved in this field. The solution of these problems largely depends on the programm-intepretaion, namely, to reconstruct the demain model and to document with new characteristics through the analyzation (black- or white-box, static or dynamic) of the old code by using advanced tools.

但我们也能很容易的发现软件维护、遗留代码的现代化改造以及软件的再工程问题等都是软件界普遍关注的话题，以上这些问题的有效解决很大程度上依赖于程序理解，即利用现代化分析工具或者转化系统对遗留代码进行白盒/黑盒、动态或者是静态分析，提取信息，获取抽象描述，从而达到重构具有现代意识的各类文档和领域模型。

Making use of this model I have a taste in Yan Shan Reservoir watershed in He Nan Province: I start on the information of the surface in this area, give every grid cell the proper parameters by distilling them from the map of how the people use soil and the map of soil type in this area; In order to get the topographical information, I add numerical value to a abundant of contour lines and points in topographical map, use the software Arc View of GIS to create Digital Elevation Models automatically, get every volume of the reservoir from the water level 99m to 117m. By using a special module of the software, I distill triumphantly the grid cells elevation value, slope value, flow direction, flow accumulation, watershed, stream network, isochrones and so on.

本文在分布式水文模型的基础上，对河南省燕山水库流域洪水入库计算模拟方面作了一些研究：从燕山水库流域的下垫信息开始着手，依据流域的土地使用类型图、土壤分布图确定每个栅格单元的土壤特性和土地利用方式，进行下垫信息的参数化，得到单元模型所需的参数值；为了提取地形信息，本文通过对流域地形图海量数据加载高程值，利用GIS软件自动生成流域内的数字高程模型，提取了流域水文模型所需要的库容曲线；通过栅格自动划分，提取栅格单元的高程、坡度、栅格流向、流域边界、虚拟河网、流量积累、等时流线面积分布等分布式水文模型的流域特征。

提出分线控制、分层解译提取信息和分步转绘制图的程序。流水线的现代沟谷缘线是决定图斑格局的最基本的特征线。图斑的形状和走线应遵照遥感影像（彩红外航片和TM卫星影像）特征，按双毫米尺度进行归并综合。

WebSQL is a SQL-like query language for extracting information from the weba Its capabilities for performing navigation of web hypertexts makes it a useful tool for automating several web-related tasks that require the systematic processing of either all the links in a page, all the pages that can be reached from a given URL through paths that match a pattern, or a combination of botha WebSQL also provides transparent access to index servers that can be queried via the Common Gateway Interfacea

WebSQL是用于从网络中提取信息的类数据库查询语言。其履行网站超文本导航的能力使其成为自动化不同网络相关任务的有用工具，这些任务每一个网页中的的链接需要被系统化的处理，所有的网页，可从某一特定的URL，通过匹配模式的路径或者两者兼有而到达。WebSQL还提供透明访问索引数据库，可通过公共网关接口来查询。
