摘要
借鉴IHS变换融合算法的改进方法和思路,提出了对Brovey融合算法的改进措施,减少了融合图像的光谱特征畸变。同时,克服了IHS变换等方法只能同时融合3个波段数据的缺点,实现了利用改进型Brovey算法融合高光谱图像和高空间分辨率影像。通过实验表明,改进的Brovey融合算法与原Brovey算法相比,不但完成了三波段以上数据的融合,而且减少了融合图像的光谱畸变,取得了较好的融合效果。
Brovey image fusion algorithm requires that the spectral response range of the respondent spectral band of the high spatial resolution Pan image is consistent with or similar to that of the multi- spectral image, or it will cause color distortion, so it limits its application in the fusion of RS data. A lot of improved IHS fusion algorithms have been introduced to solve the problem, but only can fuse three multi-spectral bands with Pan data. In this paper, the authors present an improved Brovey algorithm which can effectively fuse multi-spectral or even Hyperion data with Pan data with less color distortion.
