Running Demo

If you want to get the results of the demo shown in webpage, you can run the following scripts. The results are saved in ./outputs/results/demos

1. Demo of Motion Imitation

   python demo_imitator.py --gpu_ids 1

2. Demo of Appearance Transfer

   python demo_swap.py --gpu_ids 1

3. Demo of Novel View Synthesis

   python demo_view.py --gpu_ids 1

Running Scripts (examples) (Details)

If you want to test other inputs (source image and reference images), here are some examples. Please replace the --ip YOUR_IP and --port YOUR_PORT for Visdom visualization.

1. Motion Imitation

   • source image from iPER dataset

   python run_imitator.py --gpu_ids 0 --model imitator --output_dir ./outputs/results/  \
       --src_path      ./assets/src_imgs/imper_A_Pose/009_5_1_000.jpg    \
       --tgt_path      ./assets/samples/refs/iPER/024_8_2    \
       --bg_ks 13  --ft_ks 3 \
       --has_detector  --post_tune  \
       --save_res --ip YOUR_IP --port YOUR_PORT

   • source image from DeepFashion dataset

   python run_imitator.py --gpu_ids 0 --model imitator --output_dir ./outputs/results/  \
   --src_path      ./assets/src_imgs/fashion_woman/Sweaters-id_0000088807_4_full.jpg    \
   --tgt_path      ./assets/samples/refs/iPER/024_8_2    \
   --bg_ks 25  --ft_ks 3 \
   --has_detector  --post_tune  \
   --save_res --ip YOUR_IP --port YOUR_PORT

   • source image from Internet

   python run_imitator.py --gpu_ids 0 --model imitator --output_dir ./outputs/results/  \
       --src_path      ./assets/src_imgs/internet/men1_256.jpg    \
       --tgt_path      ./assets/samples/refs/iPER/024_8_2    \
       --bg_ks 7   --ft_ks 3 \
       --has_detector  --post_tune --front_warp \
       --save_res --ip YOUR_IP --port YOUR_PORT

2. Appearance Transfer

   An example that source image from iPER and reference image from DeepFashion dataset.

   python run_swap.py --gpu_ids 0 --model imitator --output_dir ./outputs/results/  \
       --src_path      ./assets/src_imgs/imper_A_Pose/024_8_2_0000.jpg    \
       --tgt_path      ./assets/src_imgs/fashion_man/Sweatshirts_Hoodies-id_0000680701_4_full.jpg    \
       --bg_ks 13  --ft_ks 3 \
       --has_detector  --post_tune  --front_warp --swap_part body  \
       --save_res --ip http://10.10.10.100 --port 31102

3. Novel View Synthesis

   python run_view.py --gpu_ids 0 --model viewer --output_dir ./outputs/results/  \
   --src_path      ./assets/src_imgs/internet/men1_256.jpg    \
   --bg_ks 13  --ft_ks 3 \
   --has_detector  --post_tune --front_warp --bg_replace \
   --save_res --ip http://10.10.10.100 --port 31102
