Haze is a typical weather phenomena that has a significant negative impact on transportation safety, particularly in the port, highways, and airport runway areas. A multi-scale U-shaped dehazing network is proposed in this research, which is based on our multi-channel feature fusion attention structure. With the help of the feature fusion attention techniques, the model can focus on the intriguing locations with higher haze concentration area. In conjunction with UNet, it can achieve multi-scale feature reuse and residual learning, allowing it to fully utilize the feature information of each layer for image restoration. Experimental resulsts show that our technique performs well on a variety of test datasets. On highway data sets, the PSNR / SSIM / L∞ error performance over the novel technique is increased by 0.52% / 0.5% / 30.84%, 4.68% / 0.78% / 26.19% and 13.84% / 9.05% / 55.57% respectively, when compared to DehazeFormer, MIRNetv2, and FSDGN methods. The findings suggest that our proposed method performs better on image dehazing, especially in terms of L∞ error performance.
雾霾是一种典型的天气现象,对交通安全有重大负面影响,特别是在港口、高速公路和机场跑道区域。本研究提出了一种多尺度 U 型去雾网络,该网络基于我们的多通道特征融合注意结构。借助特征融合注意技术,模型可以关注具有更高雾浓度区域的有趣位置。与 UNet 结合使用,可以实现多尺度特征重用和残差学习,从而充分利用每个层的特征信息进行图像恢复。实验结果表明,我们的技术在各种测试数据集上表现良好。在高速公路数据集上,与 DehazeFormer、MIRNetv2 和 FSDGN 方法相比,我们的新技术在 PSNR/SSIM/L∞ 误差性能方面分别提高了 0.52%/0.5%/30.84%、4.68%/0.78%/26.19%和 13.84%/9.05%/55.57%。研究结果表明,我们提出的方法在图像去雾方面表现更好,特别是在 L∞误差性能方面。
