为恢复雾天图像对比度和颜色,更好地提取图像中的信息,根据海上开阔海域的特点,利用3维到2维透视投影模型,推导了海上图像任意像素点景深的计算公式,并结合暗原色先验知识,有效解决基准景深点的选取和天空亮度的选取问题,最后基于相对景深模型和大气散射模型,对单幅雾天图像进行清晰化处理。通过大量雾天降质图像的实验验证,该算法的去雾效果优于基于暗原色先验统计方法的效果。 更多还原

【Abstract】 It is important to extract the information from images which have poor contrasts and colors acquired in bad weather.This paper proposes an effective method to remove haze from a single input image.First,focusing on sea images with deep and wild view,the formulas of relative depth are given based on a projection model from 3D to 2D.Then,using the dark channel prior,the sky intensity and reference depth can be obtained more accurate.At last,the degrade images can be recovered by relative scene dep...
