* Standard illuminant A, CIE: A tungsten filament lamp operated at a color temperature of 2856 K, approximating a blackbody operating at that temperature.
(24) The CCW defines an incendiary as "any weapon or munition which is primarily designed to set fire to objects or to cause bum injury to persons through the action of flame, heat, or combination thereof, produced by a chemical reaction of a substance delivered on the target." (25) "Incendiary weapons do not include: (i) Munitions which may have incidental incendiary effects, such as illuminants, tracers, smoke or signaling systems." (26) Even though WP is primarily designed to be used as a smoke screen or illuminant, (27) it has been used for other purposes, such as in Fallujah where it was used to flush combatants out of hiding.
If we ignore the correlations introduced by the interpolation, the relative uncertainty of the integral with the D65 illuminant (interpolated to a I nm grid with a cubic-spine routine), reduces to 0.074 %, a value too low by the order of [square root of (5)].
The characteristics of light reflected by surfaces depends on two factors: (1) the spectral distributions of the illuminant, and (2) the spectral distributions of the surfaces reflectance.
The reflection values that are measured over the spectrum are converted into the standard or values X,Y,Z in connection with the chosen illuminant. While Y corresponds with lightness, X and Z cannot be clearly associated with hue and saturation.
The growth of the industrial sector therefore expanded the markets for whale products directly, while the increases in population, in the number and size of cities, and in per capita income that were associated with industrialization raised the demand for illuminants and other final products made from the blubber and bone of whales.1
CIE S005/E-1998, CIE standard Illuminants for Colourimetry (1998).
The function which does this performs a RGB to CIE XYZ space conversion and then from there the CIE XYZ values are transformed to CIE Lab illuminant using illuminant D65.
The VeriVide light booth (Model: CAC 120) was considered as the third setup for evaluating the blackness of the metallic black panels while a fluorescent daylight simulator simulated the D65 standard illuminant as the light source.
The CIE standard illuminant D65 was employed to construct the first three dimensions of the four ICSs.
Some of the most popular approaches in shadow removal were based on color constancy conditions as the lightness algorithms, in using a so-called illuminant invariant approach [14].
That's why the LRC recommends using two metrics: CRI, which measures how similar a light source renders colors compared to a reference illuminant, and the gamut area index (GAI), which evaluates the relative area enclosed by sample colors on a chromaticity diagram when rendered by the source.
