提出了一种基于小波变换的多光谱图像与高空间分辨率图像融合方法。该方法通过局部方差准则利用加权平均将高空间分辨率图像和多光谱图像经小波分解的低频分量进行融合,然后将融合的低频分量和高空间分辨率图像的细节分量结合进行小波反演变换得到融合图像。通过和WT方法的融合结果进行对比评价,表明了该方法在提高多光谱图像的空间细节表现能力和保持光谱信息上都有很好的效果。
A multi-spectral image fusion method based on wavelet transform and high spatial resolution image is proposed. This method uses the weighted average to localize the high spatial resolution image and the multispectral image by the wavelet transform, then combines the fused low frequency component and the detail component of the high spatial resolution image to get the wavelet transform transform Fusion image. The comparison and evaluation of the fusion results with the WT method show that this method has a good effect in enhancing the spatial detail performance and maintaining the spectral information of multispectral images.
