| 摘 要： | 本文提出了两种基于雾气理论的视频去雾新算法,一种视雾气为覆盖在各帧图像上的一层遮罩被从原视频中减除,一种视雾气为光路传播图被分离消除.前者将Retinex算法得到的亮度图像与视频帧自身的深度关系相结合求取雾气遮罩,并将此遮罩从原视频帧中分离以去除雾气;后者将由背景图像得到的视频“通用”传播图应用于视频的所有帧以消除雾气...

| Abstract: | In this paper,we proposed two new video defogging algorithms based on fog theory.One is regarding fog as the veil layer to be subtracted,and the other is taking fog as the transmission map to be separated from the original video.The former uses the luminance component image obtained by Retinex algorithm and the depth information of the original video frames to separate the veil layer.The latter applies a single transmission map obtained from the background image to a series of video frames.Experiments show ... |
