Uncensoring through neural networks

[ittaku]

Well, I wasn't really sure what subsection to put this in but anyway it's still relevant to visual novel talk. This software uses a neural network to recreate censored images. There have been previous similar posts from early versions of this software but it's now actually quite usable. See my post here on reddit:

https://new.reddit.com/r/visualnovels/comments/9sjlut/deepcreampy_decensoring_hentai_with_deep_neural/

The long and the short of it is that considering it takes about 10 seconds, it can be used as a starting point for graphic editors to then make a more reasonable decensored image, while still preserving the bulk of the original artist's "impression." No it doesn't look great, but in the absence of original work from the companies, it can be used as the basis for another graphic artist to polish up a decensored version for a localised release.

Here's the only sample I've tried it on, NSFW of course:

I assume this is a mosaic tool and doesn't decensor black-bars or white-filled censorships?

Technical progress nonentheless, impressive.

No, it can. Sometimes even better.

Here thread with examples. NSFW of course.

Oh wow, that's super great. You can even do black/white if you convert it to RGB first. The future has come and so have I.

EDIT: @ShinRaikdou, you may wanna put that link into a spoilers just in case. That's how we do NSFW around here.

I haven't tested the tool. but the neural network used have been used before and usually is pretty slow I believe?

Nope. Admittedly my computer is high powered, but a single censored spot on that first example I gave took only 10 seconds. Even on a slow computer it wouldn't take more than a minute. The more censored spots the longer it takes. It took me about a minute personally to "green out" the mosaiced part so that wasn't a lot of work either. You can get these results in less than 5 minutes per CG then once you are familiar with it.

its worth giving it a try before redrawing

As an amateur hobby editor, redrawer and shitposter, I feel like even a bad result from the program would be a better starting point for a redraw than the mosaic.

That was entirely my point and why I think this is more than just fanciful wishful thinking and pipe dreams of software giving us dicks and pussies in place of blocks.

It's mainly for bar removal and does it decently well. It can't fully reconstruct large missing portions of the graphics, but does it exceedingly well on small bits and pieces.

[ittaku]

I actually have a mechanism I use that decreases the censorship without any redrawing, but it's labour intensive. I should see what happens if I combine the two processes together to see if the results are any better...

EDIT: I tried, and the two techniques fight each other and the outcome is worse. Oh well.

Just for reference, here is my softened mosaic sample.

...it takes about 10 seconds

The most advanced neural network known to science is the human brain, and it can reconstruct images nearly instantly using the power of imagination.

Impressive, from a technical standpoint.  Removing non-random and simple random mosaics has been possible for a while, but re-constructing blocked segments is impressive.

Still, my first reaction at looking your samples pics could be summed up as: "Oh my God!  I thought they were human!"

Considering how little effort most artists put into the parts they know are going to be censored, I'm not sure 'decensoring' is an improvement.
