| 摘 要： | 将DCT应用于遥感图像中全色光学图像和多光谱图像的融合上。首先，对配准的两幅图像做DCT变换；在变换域内，通过灵活的选择全色光学图像的高频部分和多光谱图像的低频部分掺入，实现对融合结果的灵活控制。并分析了将清晰度作为判断最佳融合结果的标准。

| Abstract: | Applies DCT to the remote sensing image fusion between the panchromatic image and the multi-spectral image. First, DCT will be performed in the panchromatic image extracting the low freqency from the I component, and the hign frequen-cy from the panchromatic image that the DCT has been performed, fuse both parts to form the fused image in transformation field. Through the experiments, definition of the fused image is treated as the exclusive standard judging whether the fused re-sult is optimum. |
