Contribution

• The first 3D-based CNN method for video stabilization without training data.
• Handle parallax effect more properly leveraging 3D motion model.
• Allow users to manipulate the stability of a video efficiently.

Setup

• Main program

  • Python3.5+ and Pytorch 1.4.0+
  • Other dependencies
    apt-get install ffmpeg
pip3 install opencv-python scipy tqdm path imageio scikit-image pypng

• PWC-Net for getting optical flow as preprocessing

  • Require Pytorch 0.2.0 with python2.7 & cuda 8 (please refer to the official PWC-Net and its issue)

Running

To test your own video to be stabilized, run the commands below. The stabilized video will be saved in outputs/test by default.

python3 geometry_optimizer.py [your-video-path] [--name default=test]
python3 rectify.py [your-video-path] [--name same-as-above] [--stability default=12]

Stability Manipulation

If you have run geometry_optimizer.py for the video, you may run rectify.py for the same video multiple times with different --stability to manipulate the stability efficiently.
