iš pagrindų pakeitė mūsų pasaulį.
microscopes have revolutionized our world.
of objects, life and structures
struktūrų pasaulį,
to see with our naked eyes.
mokslui ir technologojoms.
to science and technology.
naujausio modelio mikroskopą.
to a new type of microscope,
nenaudojami optiniai lęšiai
like a regular microscope
and image processing
ir vaizdo apdorojimą,
and color changes in objects and people,
spalvų pakitimus daiktuose bei žmonėse.
plika akimi.
for us to see with our naked eyes.
in a completely new way.
į pasaulį kitu kampu.
sakydamas spalvų pakitimai?
changes its color very slightly
nežymiai keičia atspalvį,
look at other people,
sitting next to you,
or their face changing color.
it appears to us like a static picture,
galima pamanyti, kad vaizdas statiškas,
through our new, special microscope,
specialų, mikroskopą
a completely different image.
in the color of Steve's skin,
odos pigmento pakitimai.
so that they become visible.
kad taptų matoma.
Stevo širdis,
Steve's heart is beating,
that the blood flows in his face.
kraujas atiteka į jo veidą.
pamatytume pulsą,
to visualize the pulse,
recover our heart rates,
and without touching the patients.
ir neliečiame pacientų.
išgavome iš naujagimio,
we extracted from a neonatal baby
nufilmuoto su paprasta DSLR kamera.
with a regular DSLR camera,
with a standard monitor in a hospital.
kraujospūdžio aparatas.
a video we recorded.
with other videos as well.
ir su kitais video.
filmo „Batman Begins"
from "Batman Begins" here
Christiano Baleso pulsą
he's wearing makeup,
we're able to extract his pulse
išgauti jo tikslų pulsą
in the light that are recorded
šviesos pokyčius
so that we can see them.
are extremely subtle,
yra nepaprastai subtilūs.
when you try to separate them
juos atskiriant
būna įrašuose.
image processing techniques
vaizdo apdorojimo technikas,
of the color at each pixel in the video,
duomenis kiekviename pikslelyje
changes over time,
of enhanced videos, or magnified videos,
sustiprintas vaizdas,
not just to show tiny changes in color,
mažus spalvos pakitimus,
that gets recorded in our cameras
kurią įrašome,
of the object changes,
when she was about two months old.
about three years ago.
to make sure our babies are healthy,
jog vaikas auga sveikas,
that they're alive, of course.
kūdikio monitorių,
when she was asleep.
with a standard baby monitor.
kūdikio monitoriumi.
there's not too much information there.
daugiau informacijos nėra.
or more informative, or more useful,
informatyviau, naudingiau,
at the view like this.
and I magnified them 30 times,
daughter was indeed alive and breathing.
kad mano dukra tikrai gyva ir kvėpuoja.
in the original video,
the breathing becomes much more visible.
kvėpavimas tampa aiškiai matomu.
a lot of phenomena
su naujuoju judesiniu mikroskopu.
with our new motion microscope.
pulsuoja mūsų kūnuose,
are pulsing in our bodies.
are constantly moving
right after my daughter was born,
mano dukros gimimo.
too much sleep. (Laughter)
we can extract
small facial expressions.
šiuos judesius
our thoughts or our emotions.
mintis ir jausmus.
mechanical movements,
mažus mechaninius judesius,
and diagnose machinery problems,
nustatyti mechanizmo problemas
svyravimą, reakciją į aplinkos jėgas.
sway in the wind and react to forces.
knows how to measure in various ways,
kaip šiuos dalykus apskaičiuoti,
motions as they happen
this new technology,
šią naują technologiją,
others could use and experiment with it.
kiti galėtų išbandyti ir eksperimentuoti.
even created this nice website
sukūrė internetinį puslapį,
and process them online,
ir jį apdoroti internetu.
in computer science or programming,
informatikoje ir programavime
su šiuo nauju mikroskopu.
with this new microscope.
just a couple of examples
a YouTube user called Tamez85.

nėštumo metu.
pulsing veins in their hands.
padidintų pulsuojančias rankų venas.
unless you use guinea pigs,
kai nadojamos jūrų kiaulytės.

it is the first rodent on Earth
tai pirmasis planetos graužikas,
by a design student at Yale.
menų fakulteto studentės iš Jeilio
if there's any difference
jos bendraklasiai.
and then magnified their motions.
o vėliau išdidino jų judesius.
still pictures come to life.
all those examples
a new way to look at the world,
galimybę žiūrėti į pasaulį kitaip,
kūrybiškus būdus, kaip juo pasinaudoti.
new and creative ways of using it.
to look at the world in a new way,
pažvelgti į pasaulį kitu kampu,
we can do with our cameras.
gali būti naudojamos kameros.
mes pradėjome galvoti,
produce tiny motions
sukelia mažus judesius,
galėtume išmatuoti?
our cameras to measure?
that we focused on recently is sound.
neseniai susitelkėme, yra garsas.
iš esmės ir yra pokyčiai.
is basically changes
travel through the air.
and they create small vibrations in them,
sukelia mažus virpėjimus juose,
and how we record sound.
sukelia vaizdinius judesius.
also produces visual motions.
that are not visible to us
with the right processing.
vaizdo apdorojimu.
dainavimo įgūdžius,
my great singing skills.
of my throat while I was humming.
gerklė, man gaudžiant.
you'll be able to see,
visi judesiai ir raibuliavimai
we can see all the motions and ripples
in producing the sound.
išskiria garsą.
gali sudaužyti vyno taurę,
can break a wine glass
frequency of that glass
taurės svyravimo dažnį.
and magnify the motions 250 times,
išdidinus judesius 250 kartų
taurė vibruoja
how the glass vibrates
to seeing every day.
It gave us this crazy idea.
davė beprotišką idėją.
išgauti garsą iš vaizdo įrašo?
and recover sound from video
daiktuose sukuria garso bangos,
that sound waves create in objects,
back into the sounds that produced them.
everyday objects into microphones.
daiktus paversti mikrofonais.
that was lying on a table,
bag of chips into a microphone
that sound waves create in it.
kuriuos sukelia garso bangos.
that we played in the room.
we recorded of that bag of chips.
nuo traškučių pakelio.
to see anything going on in that video
ką nors pamatyti šiame video
analizuodami
to recover just by analyzing
iš video signalų.
from video signals.
of the scale of the motions here,
judesių amplitudę.
of chips to move less than a micrometer.
suvirpėti mažiau nei 1 mikrometrą.
dabar mes pajėgūs išgauti
that we are now able to pull out
atsimuša nuo paviršiaus
bounces off objects
objektų, pavyzdžiui, augalų.
from other objects, like plants.
whose fleece was white as snow,
vilna buvo balta kaip sniegas
avinėlis sekė paskui."
that lamb was sure to go.
that speech again recovered
of that same bag of chips.

ABOUT THE SPEAKER
Michael Rubinstein - Research scientist, GoogleComputer scientist Michael Rubinstein and his team have developed a "motion microscope" that can show video footage of barely perceivable movements, like breaths and heartbeats.
Why you should listen
Michael Rubinstein zooms in on what we can't see and mangnifies it by thirty or a hundred times. His "motion microscope," developed at MIT with Microsoft and Quanta Research, picks up on subtle motion and color changes in videos and blows them up for the naked eye to see. The result: fun, cool, creepy videos.
Rubinstein is a research scientist at a new Cambridge-based Google lab for computer vision research. He has a PhD in computer science and electrical engineering from MIT.
