 bokeh-camera

If you think the Google/Zoom segmentation-based background blur
effects look kind of fake, this attempts to simulate a more
realistic-looking bokeh using a RealSense D455 (for best results) or
D435 camera on a virtual camera device that you can use from any
conferencing software.

Work in progress, code not yet cleaned up, but roughly:

 1. Build requirements:

      + librealsense2-dev
      + libopencv-dev
      + cmake
      + g++ (or similar C++ compiler)
 2. Run ./build-this

 3. Ensure that you have the v4l2loopback kernel module

      + Ubuntu: sudo apt install v4l2loopback-dkms
      + Fedora/RHEL: sudo dnf install v4l2loopback
 4. Set up a v4l2 loopback device at /dev/video20

    sudo modprobe -r v4l2loopback  # This one can fail if the module isn't loaded, that's okay
    sudo modprobe v4l2loopback devices=1 video_nr=20 exclusive_caps=1

 5. Run `./BokehCamera

 6. Select the virtual camera on Google Meet or Zoom or whatever you
    use

 Controls

While it is running:

Press 1 to send bokeh-fied image

Press 2 to send a map of the computed amount of blur (white = don't
blur, black = full blur)

Press 3 to send the depth map

Press 4 to send no-bokeh RGB

Press [ or ] to refocus the image

Will it work on a D415/L515/T265?

Probably not but go ahead and try, hack at it, submit a pull request.
