That's really cool. Looking forward to seeing what GCHQ do with it. |

I answered the phone to someone from GCHQ one no joke i was only about 18 was really scary they wanted to talk to my brother |

yes its ripe for abuse i reckon, i hope they can find some cool applications for it as well, i can imagine it might be useful for science as well |

when crime watch used to be on. they pixelate the vicitms they interview I could always get more detail by squinting my eyes. i always thought why the hek dont they just use a black square? why are they allowing me to use my special powers? ....I can see them!! |

well really what we should be saying is ...yes use a swirl!! and have that message spread across the net so that people like that use a swirl!! hey can you see more of a pixelated image if you squint your eyes? does your brain fill in gaps and join dots? |

yes i reckon its similar to pareidolia where you see a face in a place where their shouldnt be a face our brain does it in real time filling in the gaps as it where |

pheww...i thought the .mpeg people might want to vivisect me and sample my brains for a few years now. |

when i was young i used to think i could see images in the static noise between channels, people talking at me in a strange tongue, turned out we were just picking up s4c on our ariel |

i know exactly where this will wind up: comp sci professors who developed these algorithms getting repeatedly flagged at airports because every "enhanced" image winds up looking like one of the guys who developed the "enhace" algorithm.... because all of the "enhance" algorithm was "trained" on digital camera images the professors took of each other in the break room. there is more than a bit of poetic justice to this |
||||||||

but, yes, that's more or less the layman summary i think you guys want: the faces it generates out of pixels are made up of loads of other faces google fed into a computer algorithms, and a bunch of math finds the best-fit for all the eyebrow flecks and occluded nostrils |

well really what we should be saying is ...yes use a swirl!! and have that message spread across the net so that people like that use a swirl!! as far back as ten years ago i've been seeing news articles where they've forensicly unswirled faces of people in child porn and gotten convictions off of it. apparently the swirl is even easier to reverse than the pixels if you want to be sure, use flood-fill to fill the offending area with black pixels. then also make sure you've cleared the EXIF thumbnail. the location data. has adaptive palette compression indicated the color of pixels you've blacked out? that could be bad |

information always leaks, but most of it gets lost as waste heat |

the JPEG algorithm is partially designed around known errors in the human visual system. just like MP3, it says: what will that sack of meat never notice i deleted? what's the visual equivalent of psychoacoustics? |

|
optimal solution: if you can perfectly simulate the whole universe in your computer, i imagine you could unpixel any image just fine (by simulating the image before it was enpixeled). |
||||||||
|
|

|
|
yeah thats a good analogy, i remember looking up about the mp3 codec a while back and its just an algorithm to delete extraneous information, i.e. frequencies that hopefully wont be notice, in a quite section of music, thats how i saw it anyway i might be wrong |
