This paper introduces the principle of the defogging algorithm and the steps of the algorithm implementation. According to the simulated image and result, the data is recorded, and the wavelet coefficient weighting is applied to evaluate the effect of remote sensing image de-clouding. Compared with the homomorphic filtering algorithm and Retinex algorithm, the wavelet coefficient weighting is applied to the remote sensing image. The effect of cloud treatment is very good.
