Abstract: Convolutional neural network is developing rapidly in image processing. Most image dehazing algorithms only focus on dehazing but neglect the overall quality of dehazing image, which leads to problems such as loss of information blurred texture, etc. To solve these problems, we propose a dehazing and enhancement convolutional neural network. Hazy image and clear image are obtained by encoding and decoding. Enhancement network is used to restore the texture and details of dehazing image. Experiments show that the proposed method has excellent results in subjective evaluation and quality indexes. Haze can be removed more thoroughly, and images with clearer details and texture can be obtained.


Key words: image dehazing; hazy features extraction; texture restoration; enhancement network; adaptive residual; channel attention

摘要:卷积神经网络在图像处理中发展迅速。 大多数图像去雾算法仅专注于去雾, 忽略了去雾图像的整体质量, 进而导致诸如信息丢失和纹理模糊等问题。 为此, 提出了一种去雾和增强卷积神经网络。 通过编码和解码获得雾层图像和一阶段去雾图像, 增强网络用于恢复去雾图像的纹理和细节。 实验表明, 该方法在主观评价和质量指标上均具有优异的效果, 获得了去雾程度更加彻底、 细节和纹理更加清晰的去雾图像, 有效地解决了信息丢失和纹理模糊的问题。
