Abstract
Satellite image fusion method and system are provided. The satellite image fusion method includes matching sizes of a panchromatic image and a multispectral image captured from a satellite image; dividing the panchromatic image and the multispectral image into a plurality of blocks; calculating coefficients to acquire Intensity (I) component image data using pixel values of each block of the multispectral image; and generating fused multispectral image data by applying the acquired I component image data to a fusion algorithm. In the multispectral image fusion, the distortion of the color information can be minimized and the multispectral image data of the high resolution can be attained. In addition, the present invention is applicable to not only the IKONOS images but also other satellite images, and the present image fusion can be carried out fast.
