Abstract
Clouds not only hide the ground but also cast their shadows on the ground, so a fast and automatic method to remove clouds and their shadows from the acquired satellite images is necessary. In this paper, a multispectral image fusion scheme to detect and remove clouds and their shadows is proposed. The entire algorithm is mainly composed of four steps: stationary wavelet transform, detection of clouds and their shadows, image fusion, inverse stationary wavelet transform. The simulation experiment shows that our method is valid and performs well.
