Static Background Replacement / Green Screen

[lmangani]

Idea for a potentially valid technique to replace a static background with a green-screen effect.

By setting all matching pixels from the static background to transparent (alpha 0) it should produce a cheap green-screen effect.

Perhaps something @benkenobi007 could be interested into? ;)

This will work until lighting conditions from the original frame change too much, ;)

@Dletta clearly its for INTENTIONAL green-scerening not on the move haha - for that you need a real green screen and it would work just as good - the loop actually blurs the $h!t out of the pixel groups to make a loose match possible - same technique used by zoom & co afaik ;)

I sit by a window, I volunteer as tester, ;)

I wrote a similar video conferencing tool https://brie.fi/ng

Maybe you'll find this Tensorflow based background blurring useful. It should be easy to adopt for replacing background also. https://github.com/holtwick/briefing/blob/master/app/src/logic/blur.js
