Mosaic is a common and widely used image/video processing method that degrades the level details of certain areas of an image/video and disrupts the patches within the area. In this way, the place where the code is played is like a small square, and people have given this kind of picture an image name: "mosaic".
Some say that the mosaic is the world's greatest invention, and some say that the mosaic is the worst invention in the world. If viewed from the perspective of existence, that is, reasonable, the mosaic exists to make some details of the image/video unrecognizable, and to protect privacy or avoid copyright risks.
Imagine what happens after the mosaic is removed again?
Today, the "mosaic remover" that appeared in magazine advertisements in the past has been announced to be reborn. This is closely related to the development of AI, Google has previously developed such an AI system, through the "association" of AI, to add details in a "guessing" way, step by step to increase the pixel multiple, and finally get a clear image.
Nowadays, with the gradual advancement of AI technology, the technology for removing mosaics has gradually matured. This has also brought about a lot of controversy, mainly focusing on the reverse intention of the invention of this technical mosaic.
The rebirth of this technology has greatly affected many industries, among which the AV industry may have suffered the most dramatic impact.

Fake sex device entities flood overseas websites
Last December, the Japanese magazine Weekly SPA! reported on the use of AI to replace the faces of well-known artists for pornography dissemination.
One trend in adult content that misuses AI technology now is to watch "decoded videos" with extremely thin mosaics. These videos are heavily uploaded by users on overseas video sites such as K and F. Among them, the untreated works of well-known actresses can also be seen everywhere, and now videos of T・S and M・Y and others can also be seen everywhere.
It is said that when these videos began to circulate, everyone was not clear what it was, let alone what impact it would have, but as the internal mechanism became clearer, the AV community was shocked.
Before approaching the truth, a few videos were actually looked up on these sites to watch first. On the website, in the works of countless vegetarians and foreigners, the names of well-known Japanese AV actresses are mixed, and the title is written in Chinese with the words "Codeless Cracking (Removing Mosaic)".
At the beginning of the picture of a man and a woman entangled, there is a veil-like layer in the part that should have been a mosaic, making the details look blurry, and the slightly unnatural deformation of the sexual organs is highlighted. Although it is easy to see that the hands and mouth are touching the sexual organs, the movements and shapes of the sexual organs are a bit strange.
The reason why there is such a video flow is actually because of the use of AI to "reproduce" the sexual organs. That is to say, the sexual organs in the video are analyzed by AI through the mosaic, in the color, shape and body angle to come up with - "I'm afraid this is the feeling", and then add "fake sexual organs" in the mosaic section. Ha Jong-ki, editor-in-chief of the technology media "ROBOTEER", said.
"To make images and videos with low definition clearer, and to make the synthesis and reproduction AI technology of a few years ago a trend, using GANs (Hostile Generative Networks)." This is different from machine learning, even if there is no so-called 'teacher data', AI can find constructs and laws from objects, and then complete them to produce data that does not actually exist. This is the technology used by software that eliminates the glare of poles and passers-by in the background of a photo without any sense of violation. ”
Popular AV actress Yuya Mikami posted on Instagram last summer, saying that "my untreated works have become a hot topic, but in fact, this is made with AI, which is a pity." In contrast, industry stakeholders are generally angry about the production and outflow of these videos.
The relevant personnel of the AV production company said, "The actresses are very pitiful, there are many people who are willing to star in THE AV because of the mosaic, if they know that their interests have been damaged, it should be very hurt." Even if you explain to them that these are forgeries, how much are they willing to believe? ”
So, where did these videos come from? Was it made by a technical engineer who is good at AI? No, now the code-removing software can be used by anyone, and it is precisely because of the "JavPlayer" video software that the relevant videos will be uploaded in large quantities.
Even if the release page of the software can be found, the true identity of the creator is still a mystery. Although many people have tried to contact, the contact address is completely unknown, and all efforts have been wasted. However, there are indications that the creators appear to be Japanese, and the published pages use overseas production services, and the outline is not very clear.
Chinese to use decoding software to rise massively?
Decoding technology was originally developed by people who worked a few years ago to eliminate graphic mosaics from pornographic games. In recent years, with the rapid development of AI technology, real-time decode playback tools have emerged.
Producers may have initially developed it out of personal interest, but since last summer, some people have added codeless VVs for profit in places such as overseas websites. A game content producer in the AI industry said.
"Reproducing the mosaic part will put a huge load on the computer, and the computer will not run well if the performance is not high. The computers they use are probably self-made high-performance computers by Chinese businessmen, and the processing of videos can be well achieved, after all, it is a capacity that cannot be reached by the average range of interests. ”
Codeless videos uploaded overseas can be watched for free, websites can get advertising revenue, and contributors can also get joint marketing revenue. Although it is a complete violation of the law, it has become a situation similar to the circulation of fake pornography reported last time.
Of course, it is no problem for individuals to use software to decode and process them for entertainment. However, if it is for profit, uploading a video on a website that is not specifically designated for viewing is equivalent to copyright infringement.
What kind of countermeasures will the AV community take to such a situation? The IPPA Bureau, an industry group that protects copyrights in adult works, said that "illegal videos must be removed, but they also need to be assisted by the police in searching." Watching illegal videos will bring losses to AV production companies, and the remuneration of performers will also be affected, and it will be difficult to produce better works in the future.
Of course, the spread of illegal content has also become a matter of life and death for creators. AV director Masaaki Hibino said so.
"Among AV producers, there are people who want to make movies and TV series but don't have the strength and talent to enter that industry, and there are also people who are rejected by the entertainment industry because of their junior high school education, and these people can eat serious food in the AV industry." How they will live without protecting copyrights, these people's 'bottom line' is gone. Copyright is important, not just for movies, but also for AV. ”
In order to achieve legal erotic images, after the invention of island cultures such as mosaics, Japanese AV has developed so far, and the current vandals have seriously threatened the AV industry.
Verify the code!
We actually tested the reproduction mosaic video tool "JavPlayer" introduced in the article, and the software is available in both a free trial version and a paid version (1200 yen). In order to reproduce the physical appearance of a video website, a high-performance computer equipped with a GPU (an image processing device using a virtual currency miner) is usually required. This time we use a normal computer to verify.
Play coded videos with this software, the mosaic part looks blurry. Although the reproducibility is low, it looks a bit clearer than the original video. When the video is played, the computer exhaust fan is buzzing, and it can be seen that the playback of the video brings a considerable load to the computer.
The software, combined with content purchased from major adult websites in Japan such as FANZA, saves videos that allow mosaics to be immediately redisplayed. The explanatory text on the release page reads "The sleeping video under the HDD (hard disk) may become a treasure", which can be clearly guessed, which means that it is a coded AV work. In addition, there is also an English commentary, and the paid version can be used by overseas payment systems, which seems to be expected from overseas users.
Although the real identity of the maker of the software is unknown, it seems that it is Japanese.
