1. A satellite image fusion method comprising:

  • 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,wherein the coefficients are calculated using a least square method based on the following equation;
