Sparse Optical Flow

There is a demo lucas_kanade.py script of Lucas-Kanade algorithm which can be run with this command:

python3 test.py --algorithm lucaskanade --video_path videos/people.mp4

Dense Optical Flow

The wrapper of Dense Optical Flow algorithms dense_optical.py can run a couple of OpenCV's algorithm implementations:

• To start the Dense Lucas-Kanade algorithm:

  python3 test.py --algorithm lucaskanade_dense --video_path videos/people.mp4
  

• To start the Farneback algorithm:

  python3 test.py --algorithm farneback --video_path videos/people.mp4
  

• To start the RLOF algorithm:

  python3 test.py --algorithm rlof --video_path videos/people.mp4
