摘要
为了对海量的多源遥感数据进行有效的管理 ,对多源遥感数据库快速准确地进行查询检索便成为急待解决的问题 .为此采用了矩特征表示形状轮廓特征 ,对多源遥感图像数据库检索进行了初步的探索 .经过大量实验表明 :使用矩特征表示形状轮廓特征进行多源遥感数据库检索 ,当待检索图像具有明显形状轮廓特征时 。
In order to manage effectively huge multi-source remote sensing image database, retrieving the desired images quickly and accurately in the remote sensing image database becomes an urgent problem to solve. A preliminary experimental investigation on a retrieval system for multi-source remote sensing image database is carried out based on the technology of content-based image searching. Moments are used to denote the shape features of images to retrieve multi-source remote sensing image database. Experiments proved that the results are satisfied when the remote sensing images searched are with distinct shape feature.
