Aimed at the uneven illumination phenomena in the remote sensing image

this paper puts forward an improved MASK dodging method based on wavelet. According to the process of MASK dodging method

this method proposed improves the modulus of wavelet self-adaptively and non-linearly in the process of the background image obtaining. Finally the experiments are given

which show that this improved dodging method can avoid the disadvantages of the method using mean in blocks as the modulus of wavelet directly

and they also show that this method in this paper can resolve the uneven illumination in remote sensing image. It can be applied in many cases.
