We have analyzed the constancy of the response ratio for cones, second‐stage
mechanisms, and CCD sensors when daylight or an artificial illuminant (A, F2, F7, and F11) …

If we study color reproduction, such as computer color matching or the appraisal of
metametric index, we wish to understand the characteristic of color differences that are …

Due to the variability in the sets of color‐matching functions, different real observers have
associated different color‐representation systems. This fact darks the true interpretation of …

We present an analytical method to analyze, from a theoretical point of view, the influence of
color‐matching functions on the perception of luminance thresholds. We show that the …

This study describes a novel method for characterizing the colorimetric and photometric
properties of three‐channel color imaging devices. The method is designed to overcome …

Forty observers determined their unique hues from arrays of Munsell chips in a standard
surround under artificial daylight. There was some discrepancy in the results of males and …

In this article, we are combining minimization criteria in the colorant separation process for
spectral color reproduction. The colorant separation is performed by inverting a spectral …

C Daylight™ glasses are designed to convert light from domestic incandescent lamps (≈
Illuminant A) to the Illuminant C phase of daylight. The efficacy of this conversion is …

Comparing colour histograms of images has been shown to be a powerful technique for
discriminating among large sets of images. However, these histograms depend not only on …

The term “color gamut” historically has been associated with color output such as optimal
color stimuli and additive and subtractive imaging systems. Recently, this term has been …
