DeepCreamPy and machine learning decensors
Posted on: 10/31/18 11:58PM
The world has changed. As of today the world's machine learning algorithm for decensoring hentai, "DeepCreamPy", was released and made publicly available. (github.com/deeppomf/DeepCreamPy) And it works, in some cases quite well.

This opens up a multitude of questions. Will machine learning decensoed pics be allowed on the site? Will they have their own tag to differentiate them from traditional decensors? What if any quality control rules will be put in place?

If you can still see a bar its still censored in my opinion. The networks aren't perfect and my guess is just dumping loads of images run through them with no cleaning at all will get deleted pretty quickly.

I'll admit to more than a fair share of bias and salt regarding these things but I'll let the mods have their say.

I'm not sure what you mean by this?

I would agree with that in most cases. The algorithm still needs work and certain types of censors are still unsupported. However, its actually very good at doing small solid color censor bars.

Here's an example imgur.com/uHqTi9Z

And even with more egregious censors it can do a passable job.

Here's an example of it failing hilariously badly: simg3.gelbooru.com//image...6d4f10ae710cb3d210044.png

Do not post images like this on Gelbooru. The algorithm seems like it could very well lead to good decensored images, but the neural network needs to be trained a lot more so that stuff like this doesn't happen.

If you can tell that an image has been decensored at all without looking at the original image, it isn't a good enough decensor for our quality standards, whether it was done by hand or a neural network. All of the examples I've seen that have been posted had noticeable artifacts left where the bars were.

This might just be me, but I see it as a potential threat to people like me who do decensors as a hobby.

tl;dr "Hurr durr I spent 3 hours decensoring something and a machine did the same job in 10 minutes"

I tried downloading the thing and I can't see the average person using this without a passing knowledge in very specific programs like Python (i.e. me), I couldn't even get this script to run because I was missing some unknown things, so until it comes with a more user friendly interface/instructions to use the thing, I can probably only realistically see scanlating groups maybe using it to decensor doujins, and not random posters on here but whatever, I'm salty as fuck.

I'll let the mods say since I'm just a nobody.

As I commented on that image before it was deleted the network certainly has potential, but people really need to clean them up before posting. Its a first step in my opinion, they still need a "human" touch.

And that actually was the exact image I was referring to when I was typing that up.

Mderms, since you're an artist with experience in doing decensors how helpful do you think this or a similar program would be at cutting down the amount of work it takes to decensor an image. I.e. what percentage of the work is still left to do compared to starting from scratch.


>If you can tell that an image has been decensored at all without looking at the original image, it isn't a good enough decensor for our quality standards, whether it was done by hand or a neural network.

I agree with this 100%, that is what the rule always has been and should remain. However, my purpose in creating this thread was to make mods and admins aware of this new tech so they can hammer out the details of how exactly to enforce it. As well as, to get a feel for the community's views on the topic.

You give me waaay too much credit. I just do the images that interest me in my free time man...

From some of the ones I've seen sometimes it can get you almost perfect results (Like this one. gelbooru.com/index.php?page=post&s=view&id=4465952. While I would've spent about 5 minutes cleaning it up or hiding the edges of whats left of the bars, its about 99% there. I can only barely still see the marks where the bars were because I knew where to look for them from the original image) and others just plain don't work very well. From the image Jerl posted, if I were so inclined I could *probably* make it post worthy in about 15-30 minutes from what the neural network did. It just takes a certain degree of intuition that a machine can't emulate.

Its good for a starting point to give your mind ideas on how to tackle it, but at the stage its at now, I just don't think you can rely on it to get perfect results by itself.



Keep in mind I'm talking about bar censors here. I'm not even going to get started on mosaics. Those are a whole 'nother monster entirely where being able to actually draw and having an intimate knowledge of the human body can come in handy. You get to look at a lot of Yaoi pics unfortunately to get a good sense of what hentai dicks look like...

Don't sell yourself short man. If you have enough skill to do a decensor your art skills are better than 99% of the population. In any case, if this program can cut down the work you need to do by ~80% then its really a game changer. As soon as the creator makes it a bit more user friendly and adds a few missing features I can see it becoming a standard first step for any artist doing decensors.

So I see that you all started talking about that decensor program I discovered on exhentai from a decensored SAO doujin using that program and saw that it was very impressive to me indeed.

And yeah, I also saw that Xalrun deleted all of my decensored drawings using that program since most of them were admittedly poorly decensored indeed (except for that Sayuri's Hatsune Miku pic, it managed to be very damn impressive apparently and many like me loved it so much).

I think this program as of now can be mostly used to facilitate decensorship of drawings a lot quicker than normal depending on the drawing you're decensoring which is a lot handy for colored doujins and drawings with many censor bars/hearts (ironically tho, it still cannot support monochromed ones strangely lol). But since I have no skill at decensoring drawings at all, no matter how they are, I was thinking about if I can either re-post all of those drawings in another booru such as xbooru or Sankaku Complex if they don't have a rule like here about not posting drawings with poor artifacts (poorly decensored edits), or if I have to make my own booru perhaps instead being all about that decensor program where anyone who uses that program like me can post all of their decensorships there, regardless of their skills and decensorship quality (at least acceptable ones to me). I might call it 'DeepCreambooru" or something like that. lol

If you screw up like the pic above, it's because you didn't turn off anti-alias. So far it works solid on bar censors but is very lacking on mosiacs. Running it on #3095618 resulted in the penises looking like the glans was merged with the shaft but I got a good result on #1549588
