In addition, a mathematical model was also proposed to evaluate spectral property of the fused production of EECN. The results were clearly demonstrated by an image fusion experiment using Landsat-5 TM and IRS-1C Panchromatic images of Beijing, China. The visual evaluation and mathematical analysis compared with Brovey transform confirmed that the fused image of EECN is quite similar in color to the lower resolution multi-spectral images, and its space resolution is the same as the higher solution panchromatic image.展开更多
