摘要/Abstract

摘要：

本文提出一种基于景深约束的单幅雾天图像去雾算法,该算法首先对退化模型进行变换以满足Kimmel变分框架的要求;其次,考虑到人眼视网膜锥细胞对绿光的敏感性,将绿光分量作为大气传输图变分求解模型的输入;最后,利用景深图像特性,在8邻域快速求解中对能量函数进行约束,从而有效提升去雾图像的视觉效果.实验结果表明本文算法在获得最佳去雾效果的同时,具有较好的实用性和较少的计算资源消耗.

关键词: 图像去雾, 退化模型, 景深, 变分模型

Abstract:

We propose a single image dehazing method based on scene depth constraint.Firstly, the initial degradation model is transformed to meet the Kimmel's variational model.Then, considering the sensitivity of the cone in human's retina to the green light, we use it as an input of the variational model of the atmospheric transmission map.Finally, in the 8-neighborhood fast solving we constrain the energy function by scene depth, so as to improve the visual effect of the result efficiently.Experiments demonstrate that the proposed method can effectively remove fog, provide good practicability and take less memory consumption.

Key words: image dehazing, degradation model, scene depth, variational model
