| 摘 要： | 针对IHS变换在QuickBird数据融合中存在的光谱扭曲问题，提出了利用Visual-Pan波段和线性加权匹配两种方法进行改进
，并给出了Visual-Pan波段方法中系数α的最佳取值范围，以及线性加权匹配融合图像的空间特征与光谱特征达到最佳效果时Pan
权值(wPan)和I权值(wI)的最佳取值。结果表明，对于Visual-Pan方法而言，当0.2＜α＜0.25时，可以获得非常好的融合效果; 而
对于线形加权匹配方法而言，当wpan=3/4、wI=1/4时，融合图像的空间特征与光谱特征可以达到最佳效果。

| Abstract: | Aimed at solve the spectrum distortion problem of the IHS method that exists in the QuickBird data
fusion, this paper proposes the utilization of both the visual-pan band method and the linear weighted matching
method for its improvement, and provides the best value range of the coefficient α in the Visual-Pan band method
as well as the best weighted values of Pan and I when the spatial characteristics and the spectral characteristics
of the linear weighted matching fusion image achieve the best result. Tests show that when the value of α is
between 0.2 and 0.25, satisfying fusion effect can be obtained, and when the weighted values of Pan and I are 3/4
and 1/4, the spatial characteristics and the spectral characteristics of fusion image can achieve the best result. |
