基于光谱特征的遥感图像检索方法研究

摘要

在遥感图像检索中，光谱特征的应用最为广泛，衣文研究了基于光谱特征进行遥感图像检索的方法；并且针对目前应用越来越广泛的多光谱、高光谱遥感图像波段多的特点，提出了基于K—L变换的检索方法，并通过实验验证了本文方法的有效性、%The spectral character is the basic character in remote sensing images, and is naturally being used the most widely in remote sensing image retrieval. Remote sensing image retrieval based on spectral character is carried out in this paper. Farther more, considering the characteristic of multi - spectral or hyper - spectral remote sensing images, K -L transformation based image retrieval method is proposed in this paper. This is also proved to be effective and time saving by the experiments.
