NVIDIA Virtual BackgroundGenerate a mask for an image using NVIDIA RTX to mask out human forms.
This node uses NVIDIA’s Virtual Background technology running on NVIDIA RTX enabled GPUs to pick out human forms in video / images and remove them from the background, outputting a greyscale mask. This eliminates the need for green screen keying, allowing for use in much broader contexts.
The background removal is achieved using AI and was primarily developed by NVIDIA for use on webcam feeds, for video calls, and streaming, so has been trained primarily on those data sources. It will give the best results on video feeds that resemble those - e.g. front shots of a person’s head + shoulders. However, it still achieves good results on a much wider range of scenarios. A 16:9 aspect ratio input feed at HD resolution is recommended for best results.
This node requires NVIDIA Display Driver version 520.00 or higher as well as the installation of the NVIDIA Video Effects SDK and AR SDK, which can be downloaded here: NVIDIA Video Effects SDK
Make sure you get the correct driver for your GPU, Turing (20XX), Ampere (30XX) and Ada (40XX) use different drivers and they are not cross-compatible.
