Apply single-band brightness variance ratio to the interference dissociation of cloud from satellite date

In satellite remote-sensing detection, cloud as an interference plays a negative role in data retrieval. A new method rooting on atmospheric radiation characteristics of cloud layer, in this paper, presents a sort of solution that single-band brightness variance ratio be used to detect the relative intensity of cloud clutter so as to delineate cloud field rapidly and exactly and, enable cloud elimination to result in the data free from cloud interference. In addition, concerning visible light data modification in cloud area, to use multi-band data fusion and infrared penetration method is a major technique herein. Finally plus the rate of data variation with its formulae and method
