For the problem of serious decline in the quality of the video image, sharpness and contrast reduction, edge blur and etc due to the atmospheric scattering of dust particles in dust environment, the paper proposes a dust image enhancement method, which combine the spatial domain and transform domain. First convert the degraded image into fuzzy domain to conduct PAL fuzzy image enhancement of global dust image; Then in the spatial domain, use the band-limited local histogram adaptive equalization algorithm to enhance the local component; Finally apply POSHE algorithm to enhance the local details. The experiment results show that the proposed method can effectively improve the dust image contrast, details and edge information, enhance the overall visual effect of the image.
