Official PyTorch implementation of the CVPR 2021 paper 'Real-Time High-Resolution Background Matting'. It produces state-of-the-art alpha mattes for humans at 4K 30fps / HD 60fps on an Nvidia GPU, given a pre-captured background image, and includes pretrained weights, datasets, and training scripts.
Use cases
- remove video background without a green screen
- real-time virtual background replacement for webcam
- extract alpha matte of a person from a photo
- segment human hair and fine details at 4K resolution
- train a matting model on VideoMatte240K
- benchmark matting inference speed on GPU
When to choose
- you can capture a clean background plate of the scene
- you need high-resolution (HD/4K) real-time matting on an Nvidia GPU
- you want a research-grade model with pretrained weights and training code under MIT license
When to avoid
- you cannot capture the background image beforehand - use Robust Video Matting instead
- you need a turnkey production pipeline with hardware-accelerated video encoding out of the box
- you have no CUDA-capable GPU
