Bounds for the dichromatic number of a generalized lexicographic product of digraphs

open access: closedDiscrete Mathematics, Algorithms and Applications, 2016
A subset [Formula: see text] is acyclic if it induces an acyclic subdigraph of a digraph [Formula: see text] and the dichromatic number [Formula: see text] of [Formula: see text] is defined to be the minimum integer [Formula: see text] such that [Formula: see text] can be partitioned into [Formula: see text] acyclic subsets.

The number of discernible colors perceived by dichromats in natural scenes and the effects of colored lenses

Visual Neuroscience, 2008
The number of discernible colors perceived by normal trichromats when viewing natural scenes can be estimated by analyzing idealized color volumes or hyperspectral data obtained from actual scenes. The purpose of the present work was to estimate the relative impairment in chromatic diversity experienced by dichromats when viewing natural scenes and to ...

The number of colors perceived by dichromats when appreciating art paintings under standard illuminants

Conference on Colour in Graphics, Imaging, and Vision, 2008
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?
