Abstract:
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: where Pan denotes a pixel value in the panchromatic image, I denotes a pixel value in the I component image, R, G, B and N denote a red band component value, a green band component value, a blue band component value, and a near infrared band component value of the pixel in the multispectral image respectively, and a, b, c and d denote the coefficients for minimizing a pixel value difference of the I component image and the panchromatic image, wherein the fusion algorithm is given by the following equation: where F(X) denotes the fused multispectral image.
