遥感图像数据库基于内容查询的研究
信息工程大学测绘学院遥感信息工程系,河南郑州450052
摘要:

在分析图像数据库信息特征的基础上,讨论了图像数据库的一般关系模型图像数据库基于内容查询的定义,提出了相应的集合代数模型,指出遥感图像基于内容查询实现的两种方案。并以GIS要素与遥感图像的空间关系为基础,着重分析了GIS支持的遥感图像基于内容查询系统的主要算子,对基于图像特征索引的内容查询,也作了一般形式化的讨论并给出了应用的系统框架。

Research on Content-based Image Retrieval in Remote Sensing Imagery Database
Abstract:

Based on the analysis of the information characteristic of image database (IDB) the general relation schema of IDB and the conception of Content_based Image Retrieval (CBIR) were investigated, and then a set model of CBIR was introduced. Moreover, two classes CBIR system were discussed. Especially, the emphasis was put on the GIS supported CBIR and a set of such querying algebra operators was presented. The system frame and the general schema of CBIR based on image feature index were discussed as well.
