Abstract

The image data of multispectral (MS) of 4 m resolution and panchromatic (PAN) of 1 m resolution can be obtained from IKONOS. The fused MS images of 1 m resolution can be obtained by applying the fusion process to the MS images and PAN image. When an existing image fusion process is applied to the IKONOS image, the distortion of the spectrum is appeared. This is because of not being reflected in 1 m MS images to obtain the reflection of spectral response between the band of MS and the band of PAN by fusion process. To solve this problem, we proposed an image fusion algorithm using steepest decent method in this paper. Our method has been succeeded to improve correlation coefficients between the original 4 m MS image and the fused MS image which present degree of spectral distortion.
