摘要
中巴资源卫星(CBERS)多光谱CCD数据与全色HR数据空间分辨率相差较大,给图像融合带来一定困难。利用锐化、高通滤波(HPF)、Brovey变换、IHS变换、主成分变换、GS变换和小波变换等方法对CCD与HR数据进行融合试验。通过定性与定量分析,探讨了不同方法的融合效果。
CBERS-02B multi-spectral CCD data are different from HR panchromatic data in resolution,which causes difficulty in image fusion.With the method of Pansharping,HPF,Brovey transform,IHS transform,principal component transform,Gram Schmidt（GS） transform and wavelet transform,the authors have tested the fusion methods for CCD data and HR data of CBERS,and the fusion results are discussed and evaluated qualitatively and quantitatively.
