We propose a fast polarimetric dehazing method based on the hue, saturation, and intensity color space. Because the intensity is unrelated to color in the HSI color space, the proposed method is used to dehaze the intensity channel of an image, while its color distortion is corrected using a color-constancy method. This method not only shows good image-information restoration capacity but also increases the dehazing efficiency. Compared with the existing dehazing methods, the proposed method can obtain the same or better experimental results and has higher execution efficiency. Our proposed method has potential in applications for real-time haze removal in images and videos.
