illumination curved images I mentioned seven or eight vagaries of of images held uh particularly by someone who can't see we're going to have to give
Flash illumination registers most obviously when the photographer deliberately calls attention to the artifice that they're employing, as here, not least
Global illumination and that-- we've kind of did a bunch of R & D at the beginning.
And that illumination , that clarity makes it into something beautiful because beauty is, of course, not a pre-determined set of characteristics.
So the illumination is the Sun.
was actually for illumination , not for power.
source of illumination , but just couldn't make it.
energy service of illumination most lighting in the United States today is still incandescent lighting when you do
It's quite unlike the illumination that comes from the sun or even from artificial lighting.
see the kind of fluctuation of illumination on its surface, if you kind of track that over a long enough period of time
But if we ask the simplest technical question about the illumination in this painting, it would be, what's the direction of illumination ?
And that gives us an estimate to the direction of the illumination .
And hence to infer the direction to the illumination you take in the painting, you put a dot in the middle of the eye,
use the shape from shading algorithms to infer what direction of illumination on that model best explains the pattern of lightness
But we then temporarily fixed the estimate of the direction of illumination , said, all right, that's the direction of illumination .
And that gives us an estimate to the direction of illumination .
because they're all taken under exactly the same illumination conditions.
deep in the forest and the idea of the illumination that the story might bring.
as he took up this new technology as providing illumination .
knew it was possible to stand back from flash's illumination , and acknowledge a potentially more sublime electrical force.
What I'm arguing is that there is a kind of illumination of the logic behind Buddhist philosophy and psychology that
that are a little more efficient than the coal to illumination and the oil to driving that I showed you earlier so that
Poincare was considered the symbol of the genius type with illuminations , you know, flashes.
It turns out humans actually are not very good at detecting direction of illumination , but these computer methods are absolutely superb,
And then we can go back and re-estimate the direction to the illumination .
And Illumination , of course, comes on.
I've already talked about Jacob Riis's desire for the social and illumination and transformation that he thought flash photography could bring about.
And then the scientists also would like to be in particular areas of illumination and non-illumination .
You do have the eureka moment, illumination , but usually there is nothing in the environment that relates to the problem that you are working on.
And the dot product, the angle between the direction of the illumination and the normal to the face,
So we do the inverse and measure that brightness and then infer the direction to the illumination .
And we temporarily assumed that was her face and then used shape from shading to find an estimate to the direction of illumination .
Then we get a better model of her face and the better model of the direction to the illumination .
Originally, I was just going to be writing a story for Illumination .
ugly or dismal that thing might be or how torturous, the illumination of it transforms it.
It also looks like the near side, in terms of its illumination .
You just need to tweak it-- so using the right optics, the right illumination , the right structures, and so on.
Because it's helped me understand what is distinctive about flash as a technological form of illumination .
But still, I did not come down from a mountaintop with any kind of special illumination , you will be happy to hear.
And so in remote sensing, we have what's called the target observer illumination geometry.
If I'm looking at the surface, I want the illumination behind me.
And if the brain has not been prepared by the hard work part, the illumination will not come.
working like crazy to make the computation work, the moments of illumination , like, ah, that's the way it has to do, the moments
So we're trying to actually try to work out how these areas correspond to solar illumination , and other things.
And I have this thing, which is the peripheral illumination , which is very cool.
the math on the efficiency of the energy content of that coal and bring it through to the delivery of illumination
The brightness in an image, like a photograph, will depend upon the direction of illumination and the normal, the perpendicular,
And I won't go through all the mathematics, but if we measure the lightness along the outer boundary, we can then infer what direction of illumination
draw a straight line, green arrow through the center of mass of the highlight, and that tells us the direction to the illumination .
But they do use the flashlights at night because that way, they have a light source of known illumination properties.
