Run time and cost

This model runs on Nvidia T4 GPU hardware. Predictions typically complete within 17 seconds. The predict time for this model varies significantly based on the inputs.


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.

Disclaimer: The video conversion script in this repo is not meant be real-time. Our research’s main contribution is the neural architecture for high resolution refinement and the new matting datasets. The script allows you to measure the tensor throughput of our model, which should achieve real-time. The script allows you to test your video on our model, but the video encoding and decoding is done without hardware acceleration and parallization. For production use, you are expected to do additional engineering for hardware encoding/decoding and loading frames to GPU in parallel. For more architecture detail, please refer to our paper.

New Paper is Out!

Check out Robust Video Matting! Our new method does not require pre-captured backgrounds, and can inference at even faster speed!
