Running code

Calculate smoothed flow using [Yu and Ramamoorthi 2020].

conda activate FuSta_CVPR2020
cd CVPR2020CODE_yulunliu_modified
python main.py [input_frames_path] [output_frames_path] [output_warping_field_path]

e.g.

python main.py ../../NUS/Crowd/0/ NUS_results/Crowd/0/ CVPR2020_warping_field/

Run FuSta video stabilization.

conda deactivate
conda activate FuSta
cd ..
python run_FuSta.py --load [model_checkpoint_path] --input_frames_path [input_frames_path] --warping_field_path [warping_field_path] --output_path [output_frames_path] --temporal_width [temporal_width] --temporal_step [temporal_step]

e.g.
