说明：  随着遥感图像数量的急剧增加, 基于内容的遥感图像检索系统逐渐成为了一个研究热点。系统地介 绍了该领域各个方面研究的现状。首先给出了遥感图像内容检索系统的基本结构和查询策略。其次,结合遥 感图像的特点,着重介绍了基于纹理、形状、结构特征相似性比较等方面的内容, 针对这些方面的研究所存在 的问题提出了见解, 介绍了所研究成果,并对今后的工作进行了展望。
(The content- basedretrieval (CBR) systemfor remotesensing images(RSI) hasbeena hot researchareare-cently withanincreasing huge amount of imagedata generatedduring the two decades . The present situationof eachre-search aspect in this area is introduced. Considering the features of remote sensing images , the structure and query strategiesof the CBRsystemfor RSI arediscussed. Similarity comparisonof the texture, shape andtopography are dis-cussed. Suggestions arepresentedto solve the existing problemsinthisfield. Some opinions about problemsexisting in this area are presentedandthe future development is described.)
