针对雾霾天气导致室外图像可见度降低的问题，提出一种快速的单幅图像去雾算法。结合图像暗原色先验理论及实时域变换滤波算法，提高了单幅图像去雾的抗噪性和实时性。基于滤波后图像的透射率估算，避免了噪声在去雾结果中的增强，对图像的白平衡处理解决去雾后图像的色偏现象，该算法可明显地增强图像内场景的可见度及细节信息。

Aiming at the problem that hazing decreases the visibility of outdoor scene images, a new fast dehazing method for a single image is proposed. By using dark channel prior and domain transform filter, the robustness for noise and real-time character is improved. The transmission map computed by the filtered image reduces the enlarging of noise. White balance corrects the color shift for dehazed image. The proposed method significantly enhances the visibility of image and retains the very fine details.
