摘要:

基于暗通道先验去雾方法, 提出一种改进的自适应基于暗通道先验去雾方法, 并使用均方误差对已有雾模型数据库中多组数据进行误差分析. 实验结果表明, 该方法对光线不足或天空等背景的图像实验效果优于已有方法, 并且恢复的图像更接近真实图像.

关键词: 去雾; 暗通道; 均方误差(MSE)

Abstract:

An improved algorithm based on dark channel prior was proposed which compenstaes the transmission estimated via dark channel prior, redefines atmospheric light via analyzing the fog images fail to recover by original method based on physical model. Experiments prove our algorithm works better than original method, especially on sunlight lacking or sky including images. Meanwhile, mean square error(MSE) was used in our method to verify the images we recovered are close to true images based on fog database.

Key words: haze removal, dark channel, mean squared error(MSE)
