Abstract(in English) When images or videos are captured in outdoors, the visibility of objects may be affected by haze such as fog. In recent years, many image processing techniques for haze removal have been researched. However, these method can’t remove haze effectively for a nighttime. In this report, we propose a nighttime dehazing method. In the proposed method, Gaussian filter with multiple standard deviations are used for atmospheric light estimation. The atmospheric light estimation is achieved based on the Retinex theory. The effectiveness of the proposed method is verified by the various experiments.
