  • Google actually already has a system to automatically detect and filter incoming nude pictures. It allows apps to blur then and you can then opt to view them. It’s a separate application and uses locally running machine learning.

    I can’t remember the name of it and if it’s just on Pixels, nor what applications it works with. Might just be for their own messaging apps or it might be more deeply integrated. If anyone is curious I’ll try to look it up after work.

    The point is they already have something similar to this they could maybe leverage.



  • I’ve just discovered another use for grain synthesis:

    Adding grain using to DVD movies with badly compressed grain.

    I just bought Breakfast at Tiffany’s on DVD and despite it being a 60s movie that should have had clean grain, it has very little and what is there looks bad because of mediocre DVD compression. You end up with some minor but distracting compression artifacts and static grain. By adding a little grain synthesis, you end up with an appearance that strangely seems more authentic and hides compression artifacts.

    Here are the results. I’ve added clips wit 0-36 strength grain synthesis strength, and I personally think 24 looks pretty good.
