The number of colors perceived by dichromats when appreciating art paintings under standard illuminants
The chromatic content and diversity experienced by normal observers when observing art paintings vary with the spectral composition of the illumination and can be estimated by quantities such as color rendering indices and the number of discernible colors. Can these estimates be extended to color deficient observers? The aim of this work was to investigate how the number of discernible colors p...
متن کاملThe Effects of Illuminants and Standard Observers Combination on Relationship between Spectrophotometric Error and Colorimetric Inaccuracy
The colorimetric error depends on the spectrophotometric inaccuracy. In this paper, a new method is introduced for determining the relationship between spectrophotometric error and colorimetric inaccuracy. The error propagation in colorimetric parameter calculation is evaluated using a linear relation between variance of reflectance spectra and CIE tristimulus values. This linear formula ca...
متن کاملLegibility of Pictograms on Coloured Surfaces Under Different Illuminants Authors
Ambient lighting conditions, under which the packaging is viewed, determine to a large extent the visual perception of the information which it carries. This paper investigated how different illuminants affect the legibility of pictograms intended for the application on different coloured packaging. 87 participants observed the pictograms on blue, red and yellow coloured backgrounds in a viewin...
متن کاملTri and tetrachromatic metamerism
Two light beams that are seen of the same colour and possibly having different spectra are said to be metameric. The colour of a light beam is based on the reading of severel photodetectors with different spectral responses and metamerism results when a set of photodetectors is unable to resolve two spectra. From a mathematical point of view, metamerism can be characterized in terms of the L, M...
متن کاملDetecting Multiple Illuminants
The presence of multiple illuminants in an image is an obstacle for many computer vision algorithms as well as most illuminant estimation algorithms. Multiply lit scenes do, however, occur in many situations, such as the presence of shadows or daytime indoor environments. Common ways to minimize the problems created by multiple lights are to perform a given task only in regions containing a sin...
