Automatic cloud detection is the first step of using the remote sensing data. In this study,a novel cloud detection method based on Logistic regression model is proposed. The stepwise regression is applied to extract the feature from the satellite image of FY-2C. The Logistic regression model is applied to detect the cloud. The result of experiment,compared with the surface observations,shows that the Logistic regression model is effective for cloud image processing,and the method is more accurate than the ...
