| 摘 要： | 为了改善雾天环境下退化图像的视觉效果,结合雾天成像模型和暗原色先验的规律,提出了一种快速的单一图像去雾算法。利用暗原色先验对大气参数进行估计,选取图像中满足条件的像素点进行透射率的估计,在此基础之上利用多元线性回归分析得到回归方程,并据此计算图像中其它像素点的透射率,从而大大减小了图像透射率估计运算量,最后根据大气参数和透射率计算得到清晰化的图像。实验结果表明,该算法相对于传统的单一图像去雾方法具有处理速度快和效果好的特点。

| Abstract: | In order to improve the visual quality of fog-degraded images,a new fast defogging algorithm is proposed taking the imaging model and the dark channel prior into consideration.Firstly,the atmospheric parameter is estimated by using dark channel prior,after that,some pixels matching conditions are selected uniformly from the image to estimate their transmittances,then,based on the attained transmittances,a multi-linear regression equation is obtained,thus,the other transmittances are computed,finally a fog-f... |
