How to unmosaic/uncensor pictures

Name: ZA WARUDO!!! 2007-07-10 21:39 ID:O7ej5oGx

Can anyone give me a tutorial on how to uncensor/unmosiac pictures ?  I'm using The Gimp as a image editor.

Unmosaic? Draw over it. Mosaic is non-reversible.

Image theory. Number theory. Information theory

However, the information IS there. To calcule a mosaic, most algorithms don't just take one pixel, but they take all the pixels that compose a mosaic block, and add them together, preserving information from every pixel, as every pixel influences the result.

What the fuck is wrong with you people? Nobody replied to my troll? WTF.

So in theroy, you can um mosaic an image if you know the algorithm!

No you can't.
Mosaic is an intense(/useless) form of lossy compression.
The original information is unretrievable.

You can recreate a mosaiced picture if it's a simple image, like a mosaiced credit card. If you use the exact same technique on an exactly same image, the end result will be the same. All you have to do is to write a script that iterates through all the possibilities and then compare it to the original. If you get a match you have a succesful unmosaiced picture...

Somehow I doubt you can do this...

wtf!?... just in case that wasn't shemeless trolling the thing is that you all fail because there are like (size of the block in the mosaic)^(over 9000) patterns that form the same block.

Theres a program that can uncensor blurred and some mosaicised pics. Its called V-Reveal

This works because there is limited numbers of possible characters, and some mosaics/blur leave too much detail intact.

Simply rectangular box the evidence away [or my favorite, extend a nearby selection of similar color/pattern over it].

God!!!-Is there someone serious here(besides me) or NO TROLL here.
All the awesome VNs, you miss all the action because of censoring.
Someone is gotta develop an algo for uncensoring!!
Some knowledge Guru help us libertize the entertainment please!!!
Someone develop the algo please!!

Holy shit all these spammers.

It's not an easy task. Seriously think for a moment about the code needed to figure out how an image was mosaiced(?) and reverse it. Thats information that I don't think can be found, at least not for the near future.

Don't change these.
