Training

• Dataset Google drive: DATASETS.

• Train CycleGAN

python train.py --dataroot ./datasets/dehazing --name run_cyclegan --learn_residual --resize_or_crop crop --display_freq 100 --print_freq 100 --display_port 8091 --which_model_netG resnet_9blocks --lambda_A 1 --lambda_B 1 --lambda_identity 0.1   --niter 90 --niter_decay 0 --fineSize 256 --no_html --batchSize 2  --gpu_id 2 --update_ratio 1 --unlabel_decay 0.99 --save_epoch_freq 1 --model cyclegan

• Train Fr using the pretrained CycleGAN

• Train Fs using the pretrained CycleGAN

python train.py  --dataroot ./datasets/dehazing --name run_fs_depth --lambda_Dehazing 10 --lambda_Dehazing_DC 1e-2 --lambda_Dehazing_TV 1e-2 --learn_residual --resize_or_crop crop --display_freq 100 --print_freq 100 --display_port 8094  --epoch_count 1 --niter 90 --niter_decay 0 --fineSize 256 --no_html --batchSize 2   --gpu_id 3 --update_ratio 1 --unlabel_decay 0.99 --save_epoch_freq 1 --model SDehazingnet --g_r2s_premodel ./checkpoints/run_cyclegan/netG_B.pth 

• Train DA_dehazing using the pretrained Fr, Fs and CycleGAN.
