Peak wavelength, FWHM, and CIE 1931 chromaticity
coordinates of the ten LEDs used as primaries, when operated alone.
Finally, the measured colour coordinates of the high-power LEDs are depicted in the CIE 1931 colour space chromaticity
coordinates a * and b * over the aging period are shown in Figs.
According to the definition, we calculate the normalized chromaticity
coordinate x, y, z in the equation below, which can be pointed in the chromaticity
Figures 1, 2 and 3 show CIE Lab chromaticity
diagrams for standard (object), recorded and edited photographs.
Furthermore, previous FHWA research has shown that field measurements of chromaticity
do not correspond to perceived color judgments made by human observers.
Software features include timeline recording, data smoothing, color measurement, chromaticity
, color temperature, external triggered pulsed-light capturing and other data handling functions.
Therefore, to validate the real smoke, in addition to using the chromaticity
for judgment, dynamic features are also usually used to distinguish other smoke aliases.
On a chromaticity
diagram, the straight line connecting the extreme spectral colors red and violet) is known as the line of purples (or purple boundarylessness); it represents one limit of human color perception (http://en.
Both are said to offer increased chromaticity
, advanced color purity and more brilliance and hiding capability.
Flatbed Shootout," with Roy Bohnen, Chromaticity
A second objective was to extend that investigation to the stimulus attribute of color by evaluating effects of chromaticity
and shape on speeded naming and recognition responses.
