HDR is a set of techniques that allows a greater dynamic range
of luminance between light and dark areas of a scene than normal digital imaging techniques.
There are also three levels of brightness that provide a wide range
of luminance.
Meizu has adopted a similar compromise on the Pro 6s for low - light photography as we've seen on other recent devices, such as the Huawei Mate 9, striking a good balance between fine detail preservation and low levels
of luminance noise.
The Nubia Z11 displays fine detail preservation, with lower levels
of luminance noise in the sky compared to the Samsung S7
Noise reduction is generally very well - controlled, too, and although a slight build up
of luminance noise is visible in areas of uniform color (such as the sky), it's not too concerning.
Very visible corner shading occurs, however, with a resulting buildup
of luminance noise in the corners, and portraits often display red eyes, as well as relatively low levels of fine detail preservation.
Emily Foges, Luminance CEO, added: «We're particularly excited about Arendt's adoption
of Luminance as the first user of the real estate functionality and our first customer in Luxembourg.»
In the latter case the Benelux firm will be making use
of Luminance's new real estate document review capacity.
Uniquely, due to the advanced nature
of Luminance's platform, it learns as it is used, so that it adapts to Bird & Bird's expertise and specialisms with no training required.
This makes it a hugely exciting time to be innovating in the sector, says Emily Foges, CEO
of Luminance.
Emily Foges, CEO
of Luminance, concluded: «We are delighted to be working with innovative, forward - thinking firms such as MAQS.
«Artificial intelligence will be crucial to maintaining competitive advantage and MAQS's adoption
of Luminance will allow the firm to continue delivering the highest - quality legal services to its client base,» she added.
Parallel trials
of Luminance alongside the manual process show a minimum 50 % in time - saving and a 90 % verified accuracy rate.
As Julie Dolan, COO
of Luminance and who also worked at the former Autonomy, explains: «Autonomy did a lot of acquisitions, so we really saw the problems involved in due diligence.»
My ultimate goal is to produce a painting that has a presence and projects a kind
of luminance that can only exist in this format.
I'm assuming these are 3 - D considerations to compensate for the loss
of luminance and definition to polarized glasses, but in 2 - D it draws attention to what isn't there, i.e., money, magnifying the plasticity of a stagebound forest and an assortment of CG creatures.
This covariation
of luminance clues the brain that it is a shadow, not an object or texture.
We may conclude that even though the visual system can make sophisticated use of such abstract properties as the physics
of luminance ratios and the statistics of segmentation required for transparency, it is «dumb» with regard to other characteristics such as color because of the happenstance manner in which its hardware (or «squishy - ware») evolved through natural selection — strong evidence against «intelligent design.»
Thus, even though the visual system does not know about color subtraction, if the luminance ratios are right, then the colors are «dragged along» with the spread
of luminance.
Scientists at the Ruhr - University Bochum have investigated this phenomenon and show for the first time how simultaneous counterchange
of luminance at the borders between object and background triggers activity waves in the visual brain.
In terms
of the luminance that would exist with physical transparency, the inner square is set to be too dark (b), appropriately dark (c) or too light (d).
If the tree shadow falls on a sidewalk and darker grass (e), the manner in which the magnitude and sign
of luminance vary along the shadow's boundary would be identical on both sides of the boundary, the shadow side and the light side.
Using an imaging procedure with high resolutions, the scientists revealed that a simultaneous counterchange
of luminance of neighboring stimuli creates a sequential activation in the primary visual cortex.
What we do know is that the odd arrangements
of luminance - based edges must somehow «artificially» activate motion - detecting neurons in the visual pathways.
If the tree shadow falls on a sidewalk and darker grass (e, on preceding page), the manner in which the magnitude and sign
of luminance vary along the shadow's boundary would be identical on both sides of the boundary, the shadow side and the light side.
Not exact matches
The blue dot on the top
of the cube and the one on the darker side are exactly the same hue, reflecting light with identical intensity, or
luminance.
This simplified view clearly shows that the blue dot on the top
of the cube and the one on the darker side are exactly the same hue, reflecting light with identical intensity, or
luminance.
It is possible that the «laws»
of perception we have explored so far evolved primarily to deal with shadows and to distinguish them from «real» objects, which would also produce
luminance differences in the visual scene as a result
of differences in reflectance (for instance, a zebra's stripes or a white cat standing on a black surface).
These results were compared with the hues, levels
of saturation and
luminance that blue tits are known to see.
«For the first time, we can now construct glare - free lamps
of high efficiency, which meet highest safety standards,» Klaus Müller, Managing Director
of Gratz
Luminance, says.
The peculiar stepwise arrangement
of edges — the variation in
luminance and contrast — in each subregion
of the image, combined with the fact that even when you fixate steadily your eyes are making ever so tiny movements, may be critical for artificially activating motion detectors.
An achromatic version (b) works equally well so long as it preserves the
luminance profile
of the colored version (in other words, as long as the relative reflected
luminance of the different patches remains the same).
But when the black spaces are replaced by a green shade with the same
luminance as the blue (previously white) spaces, the 3 - D character
of the image falls apart (right).
Using a grayscale version (right)
of a similar painting, Livingstone showed that the weird colors work because they have the correct
luminance.
Those
luminance relations, which we use to make sense
of the image, are apparent in a grayscale version
of the painting (right).
It is possible that the «laws»
of perception we have explored so far evolved mainly to deal with shadows and to distinguish them from «real» objects, which would also produce
luminance differences in the visual scene as a result
of differences in reflectance (for instance, a zebra's stripes or a white cat on a black mat).
It is incapable
of applying the physics
of color subtraction, partly because color perception evolved much later in primates and did not get wired in adequately and partly because in the
luminance domain color overlap is much less common in the natural world than transparency and translucency are.
We have contrived it so that in g the overlapping region has 25 percent
of the background
luminance, as it should be if we were dealing just with
luminance.
In f and g, we have two bars crossing each other, both with
luminance of, say, 50 percent
of the background.
Interestingly, although our perceptual mechanisms seem to be aware
of the physics
of transparency pertaining to
luminance, they appear to be blind to the laws pertaining to color «transparency.»
BLUE BLUFF The blue dot on the top
of the cube and the one on the darker side are exactly the same hue, reflecting light with identical intensity, or
luminance.
• Two iterations
of L - R deconvolution (sharpening) algorithm using CCDsharp were applied to the
luminance image.
Data was expressed in table form as mean percentage
of SC area possessing a
luminance threshold below a particular level.
To measure
luminance threshold, single and multiunit activity was recorded in the superior colliculus (SC) at approximately P100 using a modification
of a previously described procedure [48].
Half
of the pairs were controlled for continuous variables (cumulative surface area, density,
luminance and overall space occupied by arrays), while the other half were not.
An Intuitive Colorimeter was made use

After her departure from

Am I correct to assume that the reason behind higher
luminance of these bulbs is better focusing - light is simply less spread out when the filament is thinner?
The maximum display
