摘要
本文提出了用DCT变换处理全色光学图像和多光谱图像的融合方法。该方法的基本思想:首先将配准的图像分块,对图像子块进行DCT变换;在DCT变换域内,对全色光学图像子块的高频部分和对应的多光谱图像子块的低频部分进行融合;最终,将融合子块组合得到融合图像。实验表明:该方法是可行有效的,取得了理想的融合效果。
The paper proposes a remote sensing image fusion algorithm based on blocked DCT between the panchromatic image and the multi-spectral image .The main idea is that firstly the registered source images are divided into a lot of blocks, and then the DCT will be carried out in each block; extracting the high frequency information from the panchromatic block and the low information from the multi-spectral block , fusion can be carried out between both blocks. Finally, the fused image can be formed by assembling the fused blocks. Experiments show that this method is used for image fusion.
