Well I have some experience in writing bots for video games and this is one of the 3 main techniques used, with packet analysis and dll injection (function / event hooks) to detect changes. You can easily look for ranges not just a specific RGB value and still do it... well not in real time for a technical definition of the term (the video doesn't run in real time either) but fast enough to keep up. Yet that part is irrelevant, if you knew about video editing you'd know it doesn't have to be done at same frame rate as the video unless you're applying a playback filter which is not what we're talking about.
That said you can forget about digital because the information is lost and it's not recoverable. In analog it seems at least theoretically possible if some old videos were only censored by moving pixels around, though you'd want to do shape (or lack thereof, finding blocks where there is no continuity and the image looks like 'noise') analysis more than specific color detection in this case.
The argument here isn't whether it is possible under certain pre-defined and unique conditions, but whether someone can go out and buy a piece of software or equipment on the market today that can be applied to any mosaic pattern and remove it (or rather, reverse engineer the original image). What you describe would hardly be universal in application as it would 1.) require that the mosaic consisted of re-arranged, but otherwise un-altered image data 2.) require new code/programming for every new mosaic and each new video and 3.) still require some modicum of manual work/input. Such a method would therefore not be very practical even if conditions made it possible.
The thing about a block is that the coordinates are known, so software could swap the colors at certain coordinates with the appropriate colors. But that would be video specific, not universal, and the AV studio itself would still need to design it that way specifically and publish the data. I also find this really unlikely in the case of analog video versus digital.
It doesn't need to be perfect to work, an image with some (potentially barely visible) artifacts is better than a mosaic and in that case you could digitise it first or indeed used specialized hardware (yes, it's possible to do editing on analog, just a lot harder and more expensive.) Knowing the pattern used to rearrange the pixels would then allow you to move them back to their original position, reanalyze for noise and test for continuity, maybe using manual input for error correction if necessary. Yet it doesn't sound very practical for reasons mentioned in this thread and due to the fact that it would only work on a very limited subset of JAVs: this does look like more of a scam than anything to me.
All the theorizing in this thread seems to depend on the claim that some JAV, which have yet to be named, supposedly re-arranged raw image data into a pattern to achieve a mosaic effect (which can be re-arranged back into the original image using the methods your describing). But can anyone here provide an example of JAV that actually uses such a method? Every JAV that I have seen uses mosaics consisting of solid colors/single RGB values.
The fallback argument is that this type of mosaic effect was only used with older JAV. This method would have been technologically and economically unfeasible for older AV studios though, if not illegal. The Japanese Supreme Court's interpretation of §175 of the Japanese Criminal Code over the years has found that while the pubic region (and pubic hair) does not need to be fully concealed by bokashi (blurring) or a mosaic, anatomical details cannot be shown. Prior to the early 90's however, pubic hair was not allowed to be shown, and so that entire region of the lower body was garishly censored in older JAV using either bokashi or extremely large mosaic blocks of solid RGB colors.
The possibility of a re-arranging mosaic effect being used therefore seems less likely the further back in time we go to apply it, since the larger mosaic blocks seen in older JAV would have been exposing way too much detail to be legal. This story only sounds believable if we assume that smaller mosaic blocks (such as what you see in present day JAV) were used, but in older JAV they were not.
Could newer JAV employ such a re-arranged mosaic method today? Technically yes, but legally I would say no. I'm no authority on the interpretation of Japanese law obviously, but common sense dictates that if these details remained intact -- albeit rearranged into a convoluted pattern -- it would still violate the wording and spirit of §175. If the AV studio used such a method of censorship fully intending for consumers to remove it then they would also be distributing adult material with the specific intent of violating §175. So, it really seems unlikely from a legal standpoint.
The bottom line is that we don't know of any JAV using this method, and even if one or two yet unnamed videos did use such a method, 99.9% of JAV on the market today does not. So, why are we theorizing anything based off this assumption/claim when it does not apply to any of the JAV people would actually have a desire to de-mosaic? The only answer to the OP is therefore "no."
Still, I don't think dismissing an idea before evaluating it is very rational and I don't think there's any need to be so arrogant about it.
I'm sorry if you interpreted my position as one of arrogance. I'm not trying to sound arrogant; I'm trying to be realistic. If I appear to have an attitude towards some of these arguments it is because I'm very skeptical of the websites making them. The last thing I want to hear about is how somebody readily believed the jargon on one of these websites and was influenced by them to pay some outrageous amount of money to import a bogus "de-mosaic" kit that doesn't work as advertised.
you know amerikajin san, I'm quite fascinated by your posts in any topic, the way you presented your POV seems the most logic to me while putting yourself in the way most of us feel :evillaugh:
LOL thanks... although I'll try to be a bit less "arrogant" in posts if this is the impression I am giving people.
I totally agree that we shouldn't waste our hopes/money on something not clearly proven/working unless japan law was changed, we're not going to see our favorite JAV actress without mosaic but a man gotta have some dream to hold on....maybe someone got a friend who was JAV producer could get it for us :moe:
Seriously it boggles me that an archaic law like this can still exist in Japan today. It is at the heart of the freedom of speech debate there though, so maybe we will see it disappear eventually. At least the interpretation of this law becomes less restrictive every few years.
