Fig. 8. Shows the dehazing results of different methods. In (a1)-(a2), foggy images from the Foggy_Cityscapes dataset are presented. In (a3)-(a4), foggy images from the 4K-HAZE dataset are displayed. In (a5)-(a6), foggy images from the DKITTI dataset are depicted. Subfigures (b) through (i) represent dehazing results using various methods: (b) Dark Channel Prior, (c) AOD-Net, (d) Wavelet-Net, (e) FFA-Net, (f) EPDN, (g) DehazeFormer, (h) the proposed method, and (i) the ground truth image
