图像去雾透射率的优化算法

在雾、霾等天气条件下，大气粒子的散射作用导致图像严重降质。本文提出一种简单快速的基于物理模型的图像去雾新算法，对大气散射模型进行化简，得到新的去雾模型。然后，利用暗原色先验方法估计大气光值A，并代入新的简化模型，得到去雾图像。实验表明，该算法在处理速度和去雾效果上都优于现有算法。

The Optimization Algorithm of Image Defogging Transmittance

In the fog or haze weather, the scattering of atmospheric particles leads to serious image degradation. This paper proposesa simple and fast algorithm based on physical model to simplify the atmospheric scattering model and obtain a new defoggingmodel. Then it uses the dark channel prior method to estimate the atmospheric light value A, and puts A into a new simplified modelto get the fog image. Experiments show that the algorithm is superior to the existing algorithm in processing speed and defogging effect.
