Analysis of the cloud background and its simulation based on the remote sensing image

The realistic simulation of the cloud background has certain difficulty because of its appearance and irregular arbitrary distribution. In order to more realistically simulate cloud background, a multi-layer "cloud particle" superposition model is proposed in this paper based on the characteristics of real cloud background. First, characteristics of remote sensing of clouds under different distribution frequency are collected and the laws within them are analyzed. Second, the generation space of the "cloud particles" that will be generated is delimited based on the fractal theory. Third, cloud images at different frequency are generated based on the characteristic laws of the real cloud images. And finally, the multi-layer images are merged by linear superposition. The method used in this paper is also with controllable coverage, the remote sensing cloud images under different coverage, therefore, can be simulated.
