And how to do it with machine ai?
That's a lengthy research paper and potentially a few hours of getting your PC setup to run a neural net, IE, installing CUDA.
If your GPU isn't at least in the 30 series, you should stop here. Deep learning algorithms rely on a powerhouse GPU with a ton of CUDA cores to function well. Without a modern GPU, it may be impossible, or take hours vs minutes per task.
As a start, we do have something called

There's also

I'm sure there are other solutions out there for deep learning decensoring, but AFAIK it's not that useful. Yet.
If you want to decensor a video, you would need to split it into frames via FFMPEG, uncensor each frame, and repack it into a video file. You can find examples of this by searching around porn sites under, "decensored" instead of "uncensored". The technology they're using is still pretty far behind. It just makes the mosaic look blurry, and only works well when the camera is up close.
Best case scenario, you manually edit the raw images individually, by hand.
Unless you're a master artist, it will probably look like shit and you'll only waste your time.
