• Step 1: Draw trajectories:

  • Draw on a black canvas:

    python draw_curve.py --name traj_0 --height 256 --width 256 --output ./outputs
    
    python draw_curve.py --name traj_1 --height 256 --width 256 --output ./outputs
    

  • Draw on an image:

    python draw_curve.py --name rose --height 256 --width 256 --output ./outputs --input examples/rose.png
    

• Step 2: Trajectory to moving points/optical flow in a video

  • A single trajectory:

    python syn_traj_with_points.py \
    --inputs outputs/traj_0/ \
    --reverse 0 \
    --height 256 --width 256 --video_len 16 \
    --output ./outputs \
    --name traj_0 
    

  • A single trajectory (reverse):

    python syn_traj_with_points.py \
    --inputs outputs/traj_0/ \
    --reverse 1 \
    --height 256 --width 256 --video_len 16 \
    --output ./outputs \
    --name traj_0 
    

  • Multiple trajectories:

    python syn_traj_with_points.py \
    --inputs outputs/traj_0/ outputs/traj_1/ \
    --reverse 0 0 \
    --height 256 --width 256 --video_len 16 \
    --output ./outputs \
    --name traj_0
