This is a powerful virtual background macOS application that uses models from the paper "Robust High-Resolution Video Matting with Temporal Guidance".
You can download the build and use the application from here.
Once downloaded, it will contain three files.
Move PowerfulVirtualBackground.app
to /Applications
.
And move PowerfulVirtualBackgroundPlugin.plugin
to /Library/CoreMediaIO/Plug-Ins/DAL/
.
