摘要
介绍了遥感图像检索中边缘特征的不同描述方法。边缘特征有两种类型:一种是边缘图;另一种是边缘方向。文中分别采用目标图像和纹理图像对不同的方法进行了实验,结果表明将两种边缘特征结合可以提高检索的效果。
This paper introduces different description methods of edge feature in remote sensing image retrieval.There are two types of edge feature-one is edge graph and the other is edge direction.Experiments done by objective and texture database of remote sensing images show the characteristics of different algorithms,and the conclusion has been made that the two types of features can be integrated to further improve the retrieval performance.
