TimeWarp - 在线视频背景替换

Replacing Real-Time the High-Resolution Meeting Background Freely.


Example comparison in a video call
Current video conferencing tools like Zoom can take an input feed (left) and replace the background, often introducing artifacts, as shown in the center result with close-ups of hair and glasses that still have the residual of the original background. Leveraging a frame of video without the subject (far left inset), our method produces real-time, high-resolution background matting without those common artifacts. The image on the right is our result with the corresponding close-ups, screenshot from our Zoom plugin implementation.

Have a Try !

➡️ Web Demo by Gradio: Matting your own images from your browser.

Scripts

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

  • inference_images.py: Perform matting on a directory of images.
  • inference_video.py: Perform matting on a video.
  • inference_webcam.py: An interactive matting demo using your webcam.

Notebooks

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.
