说明：  提出了一种基于雾气遮罩减除的图像去雾算 法。首先对降质图像平滑滤波以估计其亮度分量，对亮度分量求均值得到均匀分布的雾气遮罩，并结合退 化图像获取与场景深度信息相关的雾气遮罩。在对数域中从降质图像中减除获得的雾气遮罩，即可得到 场景的反射图像。对反射图像进行自适应的对比度拉伸，可以得到最终的去雾结果。
(Proposed algorithm based on the image to fog mist mask subtraction. First, the degraded image smoothing filter to estimate the luminance component of the luminance component averaging get evenly distributed mist mask, combined with the degradation of image acquisition and scene depth information related mist mask. In several domains of fog deducted obtained from degraded image mask, you can get the reflected image of the scene. The reflected image adaptive contrast stretching, to get the final result of the fog.)
