| 摘 要： | 针对实际应用中因融合方法选择不恰当而无法充分发挥高分二号数据优势的问题,对常用影像融合算法进行了分析评价,旨在寻找最适用于高分二号数据的影像融合方法。采用Brovey变换、改进IHS变换、PCA变换、GS、HPF、小波PCA、Ehlers、Subtractive、HCS、NND 10种影像融合方法对高分二号影像进行融合处理,并从定性和定量两方面对融合结果进行质量评价。结果表明,针对高分二号数据,综合考虑光谱保真度和空间细节表达以及目视效果,HCS和NND方法的融合效果最佳。

| Abstract: | According to the fact that inappropriate fusion method can't give full play to the advantages of GF-2 data,this paper analyzes and evaluates the common image fusion algorithms,aiming at finding the most suitable image fusion method for GF-2 data.10 methods of data fusion,such as Brovey,modified IHS,PCA,GS,HPF,wavelet-PCA,Ehlers,Subtractive,HCS and NND,are explored in this paper to process GF-2 multispectral and panchromatic images,and the fusion results of each method are evaluated by qualitative and quantitative comparison and analysis.The results show that the methods of HCS and NND can get the best results with both more spectral information and more spatial details. |
