Abstract In the rainy and foggy areas,the images acquired by GeoEye-1 satellite are often affected by haze. Because of the influence of the absorption,refraction,reflection and scattering role of the haze on the electromagnetic waves,the image clarity is decreased. Therefore,it is necessary to eliminate the impact of the haze on the image as much as possible so as to effectively improve the quality of images. Using ENVI software as an image processing platform,the authors selected the "homomorphic filtering" and "wavelet transform" methods commonly used in China and abroad and the "band calculation composition" method proposed in this paper to make a comparative study of the effects of haze elimination for the GeoEye-1 image. The results show that the use of "band calculation composition" to remove the haze from GeoEye-1 image has a good effect.
