I am very sorry, if I created already existed thread. Why in English localizations of minori and maybe in some other Japanese VN companies mosaic still remains? And how I can remove it with special programs? Please help me! Thanks!!Last modified on 2018-11-19 at 15:15

There are some decensor programs out there, don't remember their name but pretty sure they are pretty shit. As for why, I would assume that most of the time it is because the developer don't want the thing under the mosaic to be shown. Maybe they have an artist who didn't care to draw the genetalia properly and the artist didn't want anyone to see his/her poor art. Maybe they are scared about reverse import, sounds like a bad excuse but I have heard people mention it. Also some companies like Denpasoft don't really seem to bother trying to convince the developers to give them artwork without mosaics for their release, from my understanding they don't give a damn about it unless they get lots of backlash.Last modified on 2018-11-19 at 15:21

But there is uncensored CGs of minori novel Natsuzora no Perseus, I saw it, have it on my hard drive. Art of decensored parts is pretty good, so problem is not in art, maybe in something else. Can you please tell me names of decensor programs and how can I delete mosaic with them?

Likely not existing. As far as I know, Minori was always lacking uncensored 18+ stuff in English releases.

Why do actual uncensored pictures exist? Same reason, as some uncensored doujinshi and the like exist. People create them. By hand.

There are various reasons, but in case of Minori they probably just don't want to share non-censored pictures with filthy foreigners (it's one of the most xenophobic company out there after all). The best MangaGamer could get are somewhat reduced mosaics in Ef (I don't know how it works in newer titles). And Sekai Project / Denpasoft simply doesn't care.

And how I can remove it with special programs?
Short answer: you can't.

Long answer: mosaic is basically a low-resolution fragment of the original picture. You can't recover original data from it - it's lost along with decreased resolution.
For example - in case of this VN, each pixel of the mosaic seems to correspond to something like ~16x16 square on the image (= 256 pixels). Image editing programs can use various algorithms to re-scale images to a higher resolution, but that process is pretty much guesswork based on math (to put it very simply, program divides 1 pixel into let's say 4 smaller ones, and tries to estimate what colors each of the new pixels should have based on surrounding pixels). That process generates a ton of artifacts, and that just turns each pixel into a 2x2 square. Good luck with reaching 16x16 like that. >_<
That said, it CAN be done - but, like #5 mentioned, removing mosaics requires some solid manual re-drawing. Programs can help a little, but in case of huge-pixel mosaics like here, it probably means pretty much re-drawing the mosaiced part from scratch. And that's most likely how those uncensored CGs from Natsuzora no Perseus you mentioned were made (by Chinese fans I guess?). I doubt it's original artwork.Last modified on 2018-11-19 at 18:49

@6 There has been recent development in everyone's favorite new computer trend, ~deep learning~, to have the AI redraw parts under the mosaics for us. It still looks rather bad and definitely needs manual touch-ups if you want people to fap to that stuff, but it's a thing that has only come about in the last month or two, so it may get better (though never as good as a manual redraw from a good artist).

But yeah, I'm willing to bet the image the OP has on their hard drive had the genitals painstakingly redrawn by an artist.Last modified on 2018-11-19 at 21:58

So, bobjr2000, can you redraw censored to uncensored CGs please? I can help you if you need it.
