Remote Sensing Image Fusion Based on DCT
基于DCT的遥感图像融合*

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.
