常用的遥感图像融合方法,如IHS变换法、Brovey变换法和主成分变换法等在实施图像融合时,均会有不同程度的光谱扭曲现象。探讨能有效保持光谱信息的EECN融合法。EECN融合法采用比值变换法,同时对参与融合的全色波段进行增强边缘,融合后的图像在光谱保持性能、分类精度等方面均较优。
Common remote sensing image fusion methods, such as IHS transform, Brovey transform, and principal component transform, have different degrees of spectral distortion in image fusion. Discuss the EECN fusion method that can effectively maintain the spectral information. The EECN fusion method adopts the ratio transformation method, and at the same time enhances the edge of the panchromatic band involved in the fusion. The fused images are superior in spectral retention performance and classification accuracy.
