The chromaticity values of the lesion pixels with respect the background skin are termed as relative chromaticity features.
During storage, it was observed that there was an increase in chromaticity values, which expresses the bark color intensity, followed by reduction on the last day of storage, indicating that there was no browning of fruits until the beginning of senescence.
The most yellow-shade iron oxide red pigment in the LANXESS portfolio is Bayferrox 502 showing highest chromaticity, both in full shade and reduction.
NTP Yellow is a new and patented high-performance pigment in the middle-yellow color space with high opacity, excellent stability, and unmatched chromaticity. RTZ Orange is an improvement in this pigment chemistry with the reddest shades for a true orange color.
Measurement capabilities include CIE 1931 and CIE 1976 colour chromaticity, gamma, white balance, contrast, flicker (VESA & JEITA), and uniformity, with a luminance measurement range from 0.05 to 5,000cd/[m.sup.2] and integration time better than 100[micro]sec.
The chromaticity component outputs of AGW and intensity component outputs of DHE are combined to form the enhanced underwater image.
Different volumes of cochineal dye (pH = 12, [5]) in 1 ml of AgN[O.sub.3] solution (10 mM, pH = 5.6) were analyzed with UV-Vis spectrometry, Commission Internationale de l'Eclairage (CIE) chromaticity diagram, cyclic voltammetry (CV), scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDS), dynamic light scattering (DLS), and X-ray diffraction (XRD).
The chromaticity coordinates can be estimated by measuring the degree of depolarization of the polarizer and the color filter.
The color scale to be used was [CIE.sub.L*a*b*], where [L.sup.*] is the brightness indicator, [a.sup.*] is the green (-) and red (+) chromaticity, and [b.sup.*] the blue (-) and yellow (+) chromaticity.
However, the deep red emission of these samples is almost on the end of the region of human eye color sensitivity, so the small influence of this emission on the color chromaticity coordinates of GdV[O.sub.4]:[Sm.sup.3+] is expected.
Specifically, the EyeOnWater Colour app or water transparency is based on the Forel-Ule colour index (FUI) system and converts the RGB channels of the smartphone water surface image into the xyz chromaticity coordinates which is used to index the colour of the water in terms of the FUI.
