摘    要:光谱保持和高分辨率保留是影像融合的两个重要问题,不同的应用可能对融合的结果有不同的要求.提出了一种基于小波变换的可调节遥感影像融合方法.该方法首先分别将高分辨率影像和多光谱影像进行小波分解,然后根据影像的特点,在小波域内进行影像融合,最后通过小波逆变换得到融合结果.通过引入可调节参数,该方法可以在细节保留和光谱保持两方面达到不同程度的平衡,在某些参数组合下,融合图像的目视效果和统计指标可以达到甚至超过传统的小波融合法、IHS变换和主成分变换融合法的效果.

关 键 词:遥感影像  融合方法  影像融合  多光谱影像  小波变换  IHS变换  参数组合  目视  高分辨率  主成分

Abstract:Spectral characteristics preservation and high spatial resolution retention are two key issues in image fusion. Different applications may require different balances between the two issues. A new controllable remote sensing image fusion method based on wavelet transform was proposed. At first, the two images were decomposed into sub-images with wavelet transform. Secondly, these sub-images were fused in wavelet space based on their characteristics. Lastly, a fused image was achieved by inverse wavelet transform. By introducing the parameters, the balance between spectral characteristics preservation and high spatial resolution retention can be achieved at different levels. With some combination of the parameters, the visual effects and the statistical parameters indicate that the fused result is slightly better than, or comparable to, those of the commonly used image fusion methods.
Keywords:image fusion  wavelet transform  controllability  SAR image  TM image
