| 摘 要： | This paper introduces the image fusion approach of multi-resolution analysis-based intensity modulation (MRAIM) to produce the high-resolution multi-spectral images from high-resolution panchromatic image and low-resolution multi-spectral images for navigation information infrastructure. The mathematical model of image fusion is derived according to the principle of remote sensing image formation. It shows that the pixel values of a high-resolution multi-spectral images are determined by the pixel values of the approximation of a high-resolution panchromatic image at the resolution level of low-resolution multi-spectral images, and in the pixel valae computation the M-band wavelet theory and the d trous algorithm are then used. In order to evaluate the MRAIM approach, an experiment has been carried out on the basis of the IKONOS 1 m panchromatic image and 4 m multi-spectral images. The result demonstrates that MRAIM image fusion approach gives promising fusion results and it can be used to produce the high-resolution remote sensing images required for navigation information infrastructures.

| Abstract: | This paper introduces the image fusion approach of multi-resolution analysis-based intensity modulation (MRAIM) to produce
the high-resolution multi-spectral images from high-resolution panchromatic image and low-resolution multi-spectral images
for navigation information infrastructure. The mathematical model of image fusion is derived according to the principle of
remote sensing image formation. It shows that the pixel values of a high-resolution multi-spectral images are determined by
the pixel values of the approximation of a high-resolution panchromatic image at the resolution level of low-resolution multi-spectral
images, and in the pixel valae computation the M-band wavelet theory and the à trous algorithm are then used. In order to
evaluate the MRAIM approach, an experiment has been carried out on the basis of the IKONOS 1 m panchromatic image and 4 m
multi-spectral images. The result demonstrates that MRAIM image fusion approach gives promising fusion results and it can
be used to produce the high-resolution remote sensing images required for navigation information infrastructures. |
