MDS地图数据库系统设计与实现

介绍了一个集图象处理、模式识别和数据库于一体的面向军用地图的信息系统。该系统包括图象的二值化、平滑、分滑、拼接、基于特征向量的相似检索和ＱＰＥ查询语言的设计。图象的表示采用逻辑图象表示与物理图象表示并存的方法；逻辑图象表示包括图象物体的关系表示和图象物体空间关系表示。数据结构采用拓扑结构；ＯＰＥ查询语言采用类似于ＱＢＥ形式，具有图象查询和相似检索的能力。

Design and implementation of map database systems(MDS)

This paper intrduces the military maps-oriented information systems,which integrateimage processing and pattern recognition and database. It includes image binarization, smooth,segmentation,matching,similarity retrieval based on the feature vector and the design of a querylanguage QPE. The picture representation uses logical image representation including relationrepresentation and space relation representation for image objects,and physical image representa-tion. Data structure of image objects uses topological structure,QPE,a query language,has imagequery and similarity retrleval,using the method analogous to QBE.
