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

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
