顾及光谱畸变的高分辨率图像融合方法研究

A Fusion Method of High-resolution Images Considering Spectral Distortions

  • 摘要: 使用高分辨率遥感图像进行像素级图像融合,在图像小波分解时,通过计算不同分解层数下得到的融合图像的熵来决定图像的小波分解层数;在图像小波重建时,引入局部相关系数,并在不同的分解层上设置不同的阈值进行有选择的高频系数替换,实现图像的像素级融合。并使用Quickbird全波段与多光谱数据进行试验,得到了分辨率高、光谱畸变微小的彩色融合图像。

     

    Abstract: The local correlation coefficient is introduced and the different thresholds at different levels of wavelet decomposition are set up, in order to reduce the spectral distortions of the fusion image,fuse multi-spectral images with a panchromatic image of Quickbird data by the proposed method.The result demonstrates that the proposed method is a good fusion method to increase information,improve resolution and reduce spectral distortions.
