Color vision is an important part of visual processing and as such, it often needs to be evaluated in the pediatric population. The information on a child's color vision status can often be a very important additional clue in establishing the correct clinical diagnosis. The basic principles of...
The linear relationship between the spectral response functions (SRFs) of a three‐colour response system and the set of the corresponding colour matching functions (CMFs) for a particular set of primaries, in the form of three simultaneous equations, is the principal fundamental approach adopted...
A color space is a three‐dimensional representation of all the possible color percepts. The CIE 1976 L*a*b* is one of the most widely used object color spaces. In CIELAB, lightness L* is limited between 0 and 100, while a* and b* coordinates have no fixed boundaries. The outer boundaries of...
With their inherent ability of serving as an internal reference, memory colors provide a very powerful concept in the evaluation of color rendering properties of white light sources with respect to visual appreciation. Recent results for example suggest fairly good correlations between...
A novel methodology is proposed to identify the distribution of the intensity of the illuminant across a real‐world image; with this information, the image can be classified as a homogeneous or nonhomogeneous lighting source. A criterion is proposed for deciding whether the illumination in the...
Light is scattered and absorbed in the atmosphere producing visual effects that increase with viewing distance. Contrast and chromatic diversity decrease with distance, thereby modifying the way objects and scenes are perceived. Although some perceptual compensation to produce color constancy of...
