the reason they are censored is mostly the our fault, Japanese were taught that sex was bad and it should be hidden. Now the porn exported to us is censored, though there are other Porn companies in japan that happen to forget that and get away with it. reply

Once I had a radical idea: Break down the video file into its frames (decompiling). Then use those still image mosaic removers (Gmask, FLmask, Kekoo, etc) for each frame, then recompile the video. But I think the mosaic used on video frames are not the same kind of mosaic used on still images. Besides, such an operation would require enormous amount of (CPU, memory) resources, not to mention the time required. It’s common knowledge by now that, there is machine sold in Japan, which can remove those pointless masks. reply

i believe there is no such thing as same setting to remove mosaics. why? 1st, the video resolution. 2nd, different level of mosaic.3rd,the quality of video. its easy to edit when your vid is 720p above. but how about the lower resolution? i think its next to impossible to de mosaic them. reply

To talk about Japanese porn movies mosaic removal, i am always at lost. Want it so much for years and give up, and wait for time to time even years for a particular porn star casted video that got released by illegal method uncensored, but that uncensored video amount would 0.0000001 % to the actual amount of video one might want to see their famous porn star videos.

They produce the most realistic passionate sex scenes, i just cant believe that Japanese female porn star would be different from rest of the world porn female stars,as they seem to be goddammnn forgotten sex is pretty much robotic if you dont know kissing. and there are so much sex playing stuffs the rest of the world need to catch up. One might say it had to do with culture yeah for sure but not for kissing and i am talking about plain kissing not even deep kissing.

The rest of the world usually dont prefer kissing as they
think it should be reserved for thier real life lover yet pretending to put up real lookalike sex performance for viewers, shit me absultely riddiculous,

One thing negative i can say about Japanese porn in particular female stars(majority especially young) cry a lot,or squint there faces. This is not true for mature or seasoned porn stars at all, as they are explosive and extremely spontaneous if one can remove the mosaic oh my god the rest of world will at there knees for mercy reply

I think its possble if the video saved in your system. You just need Player which reduce the Mosaic effect.
I still remember in early 20s discovered a television which can completely remove the mosaic in news chanel & other videos. But the Television banned in a week.
Please try for the playerwhich can reduce the effect of mosaic.

All of the “think about it logically: you cant” people are uncreative, restricted thinkers, and innumerate.

If it is a movie, you can do far better than interpolating and smoothing. You are thinking in 2 dimensions, you ignore the third (time).

The contents of the next frame are often very similar to those of the previous frame, if you had a non-moving object and a stationary low-res camera with slight vibration, you could compose those images into a perfect high-res image. (And real scientists do all the time.)

The mosaic section is a small part of frame, so you can get motion information from the surrounding uncensored regions. Use that to align the censored bits and then smooth (or something smarter) in the time dimension.

Best of all, a brief check of mosaiced jap videos shows that the large pixels are only in full large pixels, never rounded. So it is easy for any non-idiot computer programmer to write a tool that locates all mosaics and their border. (And not so hard even if rounded.)

This will break down with sudden motion, and be nearly perfect when the subject holds still and the camera moves slowly.

duh.

(Also, if it is just blurry, you can learn a deconvolution filter. Conceptually, also duh, in implementation, maybe harder.) reply

math dude, you talk very well indeed, why don’t u show us some of your work? it’s easy to theorize something, far harder to put it into practice. reply

Feedback


Bullshit dumbass. You didn’t make anything for removing Mosaic or you’d be rich idiot. Go scam elsewhere dipshit reply

A device COULD work if the mosaic is a deliberately weak and low-tech “encryption” algorithm (vs obstruction/destruction of the source pixels with smthn different - like the 'white space' of oldskool hentai manga, or the tacky and shit-all-obscuring ironic 'black crossing bar' of modern hmanga)

Most likely, the manufacturer of the censoring device used in many pornos leaked the technology, or even manufactured the de-censoring device themselves.

NOTE: probably will NOT work well, or at all, on re-encoded/compressed video like streaming online content, mp4/avi/mkv/etc, or analog like VHS

The sole reason a pixel-encrypting / rearranging “mosaic” would be easily beatable on DVD or BluRay is that the whole thing is a digital affair with every pixel precisely coded. Every frame of every copy match each other... hence, if the manufacturers leaked the formula that rearranges the pixels into mosaic, a reversal will obtain a stable result.

Now if it were an oldskool thing with someone literally taking a razor blade or airbrush to every frame of the master tape to censor it...forget it. Or do it the manga-translators' way: get someone to digitally redraw it from imagination. reply

Feedback


PS it will only work on mosaics made by machines built by (or leaked to) the device’s manufacturer... other similar-looking technologies won’t be affected.

Cuz it’s a reversal of a known formula set (duh), not a fantastical magical uber-hacking all-code-breaking supergadget. reply
