| 摘 要： | 为了提高SAR影像的解译水平,本文利用Contourlet变换在影像表述上能够弥补小波变换不能有效捕捉二维空间实体的特点,提出了一种基于Contourlet与HIS变换的SAR与多光谱影像融合方法.实验选取了一组TM多光谱影像与ERS-2SAR影像进行融合研究,并将融合结果与基于HIS变换、DWT结合HIS变换融合方法的融合结果进行视觉比较与统计分析.结果表明,无论是目视比较还是统计分析,本文方法都很好的将SAR影像的空间细节与多光谱影像的色彩信息集成到了一起,显著地提高了SAR影像的解译水平,相对于基于HIS、DWT+HIS变换的融合方法获得了更好质量的融合影像.

| Abstract: | To improve the interpretability level of SAR image,in this paper,a method based on Contourlet and HIS transformation is proposed to fuse SAR image and multi-spectral images,because Contourlet transformation could make up the defect that two dimensional wavelet transformation could not capture effectively the characteristics of spatial entities in the image,while the fusion method based on wavelet transform was one of the most popular fusion method in the past 20 years.The experiment selects data sets of TM ... |
