【Abstract】 Cloud removal is usually one of the necessary preprocesses before the application of remote sensing images to the extraction of land surface information. Based on the formation mechanism of remote sensing images, this paper has put forward an improved homomorphic filtering method for reducing the influence of thin cloud on images and reflecting the land surface more truly. An experiment indicates that the method can achieve better results and perform more efficiently than traditional methods.更多还原
