Two samples are also
metameric if they match to one observer but not another under the same light source and viewing conditions.
Relative LED flux powers for the WLL
metameric to reference DAY and A sources are presented in the Table 1 and Table 2.
In fact, the Phylum Annelida has many thousands of species, all of which have segmented, or more correctly,
metameric, bodies.
Also, future research will include possible
metameric effects at tertiary colours as well it's application in graphic reproduction.
Some of these are (i) transparent window (ii) optically variable devices (iii) shadow images (iv) embossed printing (v) use of metallic,
metameric or metachromic inks etc.
First and second derivative functions of the spectra also can assist in identifying inflection points and help in the discrimination of
metameric samples.
There, delta E values of perhaps 0.2 and 0.3 might be specified, also taking into account any
metameric effects.
An unsatisfactory aspect of two-dimensional representations is that they predict the existence of "
metameric" facial expressions which can be produced by more than one combination of prototype expressions, but these are not observed in practice (Morishima, 1996; Young et al., 1997).
For the Poaceae, this
metameric subunit is the phytomer (Moore and Moser, 1995; Boe et al., 2000).
Where rubber products must be produced to closely match materials that were colored with totally different types of colorants, one may well obtain a
metameric match.
According to Martin and Yuan (1996), the spinal epidural space is a
metameric segmented structure, not a uniform space (Fig 1).
The Leda line continues to expand, but at present it includes edge-glow,
metameric, translucent, metallic, metal-flake, sparkle, and fluorescent color effects.
