Virtual Background using webcam

Leave a comment

I made a webpage to produce virtual background with webcam.

https://knok.github.io/virtbg/

Sorcecode:
https://github.com/knok/knok.github.io/tree/master/virtbg

Some online meeting software (Zoom, Microsoft Teams) supports virtual background, but I want to use other software like Jitsi (or google meet), so I made it.

To make this, I referred the article “Open Source Virtual Background”. 
The following figure is the diagram.

It depends on docker, GPU, v4l2loopback (only works on Linux), so I want to make more generic solution. To make as a webpage, and using OBS
Studio with plugins (obs-v4l2sink, OBS-VirtualCam or OBS (macOS) Virtual Camera) you can use the solution on more platforms.

To make as a single webpage, I can reduce overhead using inter-process commuication using http via docker.

This is an example animation:

Unfortunately, BodyPix releases only pretraind models, no training data.

I need more improvements:

  • Accept any background images
  • Suppot choose camera device
  • Useful UI

I had attend to Cross Distribution Developer Camp 2019 Fall at Manazuru-machi, Kanagawa at 16th Nov. 2019.
There was 8 developers from openSUSE, Ubuntu, LibreOffice and Debian. We had talked about some problem between such distributions, upstream software, especially Japanese (or CJK) specific things.

Leave a comment

I had attended to Tokyo area debian seminar #157. The day’s special guest is Chris Lamb, the Debian Project Leader in 2017. He had attended to Open Compliance Summit, so we invited him as our guest.

The following pdf file is the day’s presentation:

And Hideki Yamane(henrich) talked about a new idea of Debian distribution ‘fresh’, pull-based rolling release. The details would be published by him in a few days.

There were some discussion, and we need to introduce more information aboud Japanese Debian/FLOSS scene, so now I am writing this article.

Anything else, I ccould get good time with debian developers and community. Our community, especially in Japan, requires more new commers, young people.

PIXELS (film)

I watched “PIXELS” in a theater. It subjects about video games,  mostly retro 80’s arcade games.

I love video games from childhood, my first game played would be Taito’s Space Invaders, I was the 4 or 5 yeas old time. It had bring me to the computer world.

Fortunately I am working at Akihabara area, so I can play the video games in the movie like Pac-man, Glaga, Cemtipede,  Donkey Kong and so on in two gamecenters, “Natsuge Museum” and “Hey (Hirose Entertainment Yard”.

Natsuge Museum is under private management so it closes week days. They focused to old games between 70’th to 90’th.

Hey is a franchised shop ownd by TAITO. They covered almost video games except medal games. You can play old games like Paper-boy, The Tower of Druaga, and newest games like Left4Dead arcade.

They correct many titles of the games in the movie, and be playable. They are my recommended place in Akihaba, if you like video games.

1Gbps FTTH

This month, I changed FTTH Internet from 100Mbps to 1Gbps. The costs is almost same as the past line.

To change the line, I had need to be witness in the construction, so I  couldn’t get time to attend DebConf 2015.

According to Speedtest.net, I can get about 300 Mbps upstream bandwidth.
