We presented a block-regression (BR) based pansharpening algorithm. The algorithm can combine a lower resolution multispectral image and a higher resolution panchromatic image both covering a same area, and produce a new higher resolution image, in which not only the color content are remained but also the spatial details are enhanced by adopting the higher resolution panchromatic image. BR algorithm can achieve a maximum enhancement of its spatial details at the expense of a minimum spectral distortion for the multispectral images. In the algorithm, the bands of the multispectral image used can not be limited and the algorithm is specially optimized for the pansharpening of very high resolution satellite image.
