Abstract—Basically, the sharpness and contrast of the video images captured in dusty weather will be significantly degraded and diminished. This paper proposes a novel image enhancement method. First convert the degraded image into fuzzy domain to global PAL fuzzy enhancement; then band-limited histogram equalization is adopted for enhancing the local component in the spatial domain; finally POSHE algorithm is introduced to enhance the details. The experiment results show that this method not only can effectively improve the contrast of dust image, but also enhance the details of edge information and get a good visual effect of the image.
