Start by cloning this repo to a directory of your choice. Note that due to the fact we're building and packaging OpenCV and ONNX Runtime the build times are quite long. Use them in order to build the plugin locally. The building pipelines in CI take care of the heavy lifting. Help is appreciated in building on other OSs and packages. The plugin was built and tested on Mac OSX, Windows and Ubuntu Linux. Some more information about how I built it: Building The pretrained model weights used for portrait foreground segmentation are taken from:

The goal of this plugin is to be available for everyone on every system, even if they don't own a GPU.

Perhaps in the future we will add CUDA support.

CUDA is not directly supported in this plugin, however it is supported by ONNX Runtime which we use.

Pure CPU inference will bring the CPU usage to >40%, which may get the machine warm or spin the cooling fans. On Mac we support CoreML for acceleration, which is available on M1 and M2 (not Intel, sorry).Currently on Windows we support DirectML, which should reduce CPU usage by 95% and effectively use the systems accelerators (GPUs if available).

If you like this work, which is given to you completely free of charge, please consider supporting it by sponsoring us on GitHub: It's easily composable with other OBS plugins to replace the background with e.g. It is using a neural network to predict the mask of the portrait and remove the background pixels. This plugin is meant to make it easy to replace the background in portrait images and video.
