遥感图像数据库基于内容查询的研究

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.
