摘要
在分析总结当前常用的遥感影像融合结果定量评价方法的基础上,本文描述了亮度信息,清晰程度,光谱信息,信息量等定量评价参数,并编程实现了这些评价指标的计算。以航空SAR影像和Landsat TM多光谱影像融合作为实验数据,进行了基于Brovey变换,HIS变换和小波变换方法的影像融合,并对结果进行了定量评价分析。结果表明,所提出的定量评价参数能够较准确地反映影像融合情况,可为选择恰当的融合方法提供科学依据。
This paper presents some quantitative evaluation parameters about brightness information,degree of clarity,spectrum distortion and richness of information by analyzing and summarizing current methods of quantitative evaluation on remote sensing image fusion.Those parameters have been actualized via a program.At last the aerial SAR image and Landsat TM multi-spectral band image are fused with Brovey fusion,HIS fusion and wavelet transform fusion.By evaluate the resultant with the parameters,it shows that the parameters can evaluate the fused image properly.And it can support how to choose the appropriate method of image fusion scientifically.
