This project aims at providing a "blurring background", a feature that is absent on most Linux implementation of teleconferencing softwares.
It runs pretty smoothly on CPU
Based on BodyPix, v4l2loopback and its Python3 binder pyfakewebcam, tfjs to tf converter and Streamlit to create a user-friendly interface.
Little example, working well with an uneven background.
To use it:
First we need to create a virtual webcam. Get v4l2loopback via
sudo apt install -y v4l2loopback-dkms
Create fake device:
modprobe v4l2loopback exclusive_caps=1
(The exclusive_caps here makes it usable in Chrome)
Clone this repo
From folder
pip install -r requirements.txt
streamlit run interface.py
In your browser, go to localhost:8051
I included one model (MobileNet with stride 16 and float50, the smallest one) You can download others by running 'get-models.sh' which I took somewhere I cannot remember (sorry for the author)
Just ctrl+F for 'bodypix' on https://storage.googleapis.com/tfjs-models to see which ones are available.
You can have a preview in browser or directly write to the fake device previously created. Open Zoom, you'll have a "Dummy Device" which you can choose to display.
