| 摘 要： | 分析了EO-1 ALI多光谱遥感影像各个波段的信息特征,根据信息量大小和波段间的相关性,联合偏度—峰度指数JSKF,提出针对ALI图像新的最佳波段组合方法。在最佳波段组合下对ALI多光谱数据与全色数据分别进行IHS、HPF、PCA和Wavelet变换融合,从信息量角度出发,按照定量指标对融合前后的遥感影像进行评价,并对融合前后影像进行分类应用。

| Abstract: | Analyzing the characteristics of information of multi spectral remote sensing image of each band of EO - 1 ALI, according to the amount of information and the correlation of each band, combined with skewness - kurtosis index JSKF（Joint Skewness - Kurtosis Eigure）, this paper raised the combined method for ALI images new best band. ALI in a combination of optimal banded the IHS panchromatic and muhispectral data separately, HPF, PCA and Wavelet transformed the integration from perspective of information, in accordance with the quantitative indicators to evaluate the remote sensing image fusion and application to categorize the images before and after integration. |
