A positive correlation coefficient only between concentration and luminosity (L*) was found and between concentration and the chromaticity
Illuminance was measured at 554 [+ or -] 2 lx, whereas chromaticity
was measured at (0.
ej] are the variations in the brightness, chromaticity
, and edge distortions of [X.
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.
Another measure of colour quality --a gamut area index (GAI) , is applicable for predicting how well one can discriminate differences in chromaticity
CIELAB color space uses a natural logarithmic function instead of a cube root function in the CIE chromaticity
equations and is mainly useful for the image segmentation of the three dimensional images (Fairchild, 1998).
(quality of color) of the material under daylight viewing conditions is generally a secondary concern, Molino said.
The excellent chromaticity
and the finely brushed stainless-steel surface highlight the character of the kitchen as a living area that, more and more, is regaining its classical significance as the centre of the house and apartment.
Pulse-width modulation can be readily achieved in vehicle lighting systems and has an advantage over filament based sources in that dimming LEDs in this way does not appreciably shift the chromaticity
or color appearance, whereas dimming filament sources will result in increased relative long-wavelength output and a yellower color appearance.
Software features include timeline recording, data smoothing, color measurement, chromaticity
, color temperature, external triggered pulsed-light capturing and other data handling functions.
