Real-Time High-Resolution Background Matting


Official repository for the paper Real-Time High-Resolution Background Matting. Our model requires capturing an additional background image and produces state-of-the-art matting results at 4K 30fps and HD 60fps on an Nvidia RTX 2080 TI GPU.





  • [Dec 21 2020] We updated our project to MIT License, which permits commercial use!



Model / Weights

Video / Image Examples


  • VideoMatte240K (Coming soon)
  • PhotoMatte85 (Coming soon)




We provide several scripts in this repo for you to experiment with our model. More detailed instructions are included in the files.

  • Perform matting on a directory of images.
  • Perform matting on a video.
  • An interactive matting demo using your webcam.


Additionally, you can try our notebooks in Google Colab for performing matting on images and videos.

Virtual Camera

We provide a demo application that pipes webcam video through our model and outputs to a virtual camera. The script only works on Linux system and can be used in Zoom meetings. For more information, checkout:

Web Demo

Developers in the community has helped us build a web demo. See Community Projects section below.


Usage / Documentation

You can run our model using PyTorch, TorchScript, TensorFlow, and ONNX. For detail about using our model, please check out the Usage / Documentation page.



Training code will be released upon acceptance of the paper.
