对单幅图像进行去雾复原过程中,需要根据大气光进一步估计计算透射函数值,从而实现复原图像的求解。大气光估计过程中存在偏差,会直接影响透射函数的求解。针对这一问题,对户外图像去雾复原结果进行分析,通过综合比较不同大气光估计值对复原结果的影响,给出基于RGB条件对大气光进行估计的方法。实验结果表明,适当选取大气光估计的区域,能更加准确获得大气光的估计值,他得复原图像具有更好的视觉外观。
Haze removal in a single frame need to compute the transmission function value based on estimation of atmospheric light. The error during the estimation of atmospheric light will directly affect the computation of the transmission function. To solve this problem, this paper analyzes the removal results according to different atmospheric light value respectively, and proposes an estimation method based on space to get the value of atmospheric light. The experimental results show that the proper selection of the estimated region will get more ac- curate atmospheric light value and make better recovery appearance.
