基于小波变换的遥感影像融合方法的比较分析

Comparative Analysis of Image Fusion Methods Based on Wavelet Transform

利用ETM+的全色和多光谱影像,对基于小波变换的常用几种影像融合方法进行了实验与分析,实验结果表明,基于小波变换和MNF变换的融合影像的光谱失真比较严重,基于小波变换和主成分变换的融合效果最好,其光谱保真效果最好。

Using ETM + panchromatic and multi-spectral images,several image fusion method based on wavelet transform is used for the experiment and analysis, the experimental results show that the image fusion method based on wavelet transform and MNF transform obtain poor image spectral distortion, fusion method based on wavelet transform and principal component transform has best effect, it has best spectral fidelity effect.
