Bodypix-Background

Adds a different background to your video feed.

This is made in part by the hard work of many people:

• Dan Oved and Tyler Zhu for the Bodypix model.
• Ben Elder and Daniel Llewellyn for their implementations

Daniel Llewellyn has the highest polish solution so far, making it easily installable under Linux as a snap package.

This solution aims for lower latency through the following ways

• Uses ZeroMQ IPC for communication between the TFJS model and the image processing
• Less transformations
• If blurred background is chosen, only the first frame is captured and blurred

Setup

First we need to install the nodejs and python parts.

npm install
pip install .

Next we need to setup the v4l2loopback kernel module for the fake webcam.

To install,

``bash sudo apt-get install v4l2loopback-dkms

If you already had an existing module, remove it so we can customize it,
```bash
sudo modprobe -r v4l2loopback

Create a file in /etc/modprobe.d/fakecam.conf and add the following:

options v4l2loopback devices=1 video_nr=20 card_label=fakecam exclusive_caps=1

Finally, load the kernel module

sudo modprobe v4l2loopback

Then we can start the script with ./start.sh.
