摘要：The humid tropical region is always under partial or complete cloud covers. As a result, optical remote sensing images of this region always encounter the problem of cloud covers and associated shadows. In this paper, an operational system for producing cloud-free and cloud shadow-free image mosaics from cloudy optical satellite imagery is presented. The inputs are several cloudy images of the same area acquired by the IKONOS or SPOT satellites. By mosaicking the cloud-free and cloud shadow-free areas in the set of images, a reasonably cloud-free and cloud shadow-free composite scene can be made. This technique is especially valuable in tropical regions with persistent and extensive cloud cover
