ASCII Art Webcam Effect for Linux
Hi everybody, english is not my first language and i'm still learning, sorry for grammar and spelling mistakes.
Like everybody else in this COVID 19 time, in my work we are practicing social distancing, so, all meetings are online. One coworker was using a background filter in Teams and i want to do the same, unfortunately, filters are not available for linux at this moment, so, i implement my own filter (for fun).
While researching how to implement filters, i found this excellent post:
https://elder.dev/posts/open-source-virtual-background/
In this post they use docker whit a model called BodyPix for generating a mask of the background, i did not like this. I remember a model called Deeplab, this model implement semantic image segmentation
https://github.com/tensorflow/models/tree/master/research/deeplab
So, i get a trained model form the model zoo
https://github.com/tensorflow/models/blob/master/research/deeplab/g3doc/model_zoo.md
I implement it and!!!!
Nice! but i find the borders too big for me, so i apply an erode filter
Deeplab v3 inference Mask + erode
Better. Next step is mix the input and the mask
The result was not perfect (good for the work), the latency was ok whit my nvidia video card.
OK Background removal finished…. What i do now ? well… I love ASCII Art! y and found this cool post:
https://wshanshan.github.io/python/asciiart/
I implement the ASCII Art transformation function in my code and this is the result:
Pretty cool.
So, next step is make this a make this behave like a Webcam, for that, we use pyfakewebcam and v4l2loopback (like in elder.dev post) and we get this:

Germany, France and UK urge transparency from China over coronavirus outbreak
German Chancellor Angela Merkel on Monday urged China to be as transparent as possible about the coronavirus outbreak, as Beijing faces mounting pressure over its management of the crisis.
Critics have accused China of downplaying the scale and scope of the outbreak when it first emerged late last year, while conspiracy theories have swirled in the US the virus could have been leaked from a lab.
Merkel urged for more information about the early days of the outbreak, which originated in the central Chinese city of Wuhan.
“I believe the more transparent China is about the origin story of the virus, the better it is for everyone in the world in order to learn from it,” Merkel told reporters in Berlin Monday.
Chinese scientists say the virus was likely first transmitted to humans at a wet market where wild animals were sold.
Unproven theories that the virus came from a maximum-security virology lab in Wuhan have been raised by US officials, including Secretary of State Mike Pompeo who has said an investigation was under way into how the virus “got out into the world”.
The Wuhan Institute of Virology has strongly rejected claims it could be the source of the outbreak, calling it “impossible”.
Chinese authorities have been accused of initially downplaying the outbreak and last week authorities in Wuhan admitted mistakes in counting their death toll and revised the figure up by 50 percent.
French President Emmanuel Macron last week told the Financial Times it would be “naive” to think China had handled the pandemic well, adding: “There are clearly things that have happened that we don’t know about.”
In Britain, Foreign Secretary Dominic Raab said China will face “hard questions” about the coronavirus outbreak, namely “how it came about and how it couldn’t have been stopped earlier”.
Australia meanwhile has called for an independent investigation into the global response to the pandemic, including the World Health Organization’s handling of the crisis.
Its foreign minister has said the country would “insist” on a review that would probe, in part, China’s response to the outbreak.
