demo Real-Time High-Resolution Background Matting^[1]

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

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.

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

• Image matting (Colab)
• Video matting (Colab)

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:

• Webcam plugin

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

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

• 单块GPU实现4K分辨率每秒30帧，华盛顿大学实时视频抠图再升级，毛发细节到位
• 整个世界都是你的绿幕：这个视频抠图换背景的方法着实真假难辨

Training code will be released upon acceptance of the paper.
