Defining Colors—Color Models
1997In the last several chapters, we have discussed in some depth three ways to describe colors: using red, green, and blue (RGB), using opponent colors (Intensity, Blue-Yellow, Red-Green), and the hue-saturation-intensity model (HSl). These color models were used to describe the physics, physiology, and perception of color vision.

Color appearance and color connotation models for unrelated colors
Color Research & Application, 2013AbstractThe purpose of this research is to investigate the color appearance and color connotation of unrelated colors. To investigate color appearance (i.e., brightness, colorfulness, and hue) for unrelated colors, 22 observers have answered their color appearance for 50 unrelated color stimuli using the magnitude estimation method.

Underwater Image Restoration Using Color-Line Model
IEEE transactions on circuits and systems for video technology (Print), 2019Underwater images typically suffer from low visibility and severe colorcast due to scattering and absorption. In this letter, a novel method is proposed to handle the scattering and absorption problems of light with different wavelengths based on the ...

Remote sensing algorithms for retrieving estimates of oceanic constituent concentrations, such as chlorophyll concentration, require as input measurements of spectral water-leaving radiance. This measurement is typically obtained from space-based sensors such as SeaWiFS or MODIS.

Human skin color has been used and proved to be an effective feature in many applications from human face detection to hand tracking. However, most studies use either simple thresholding or a single Gaussian distribution to characterize the properties of skin color.

The first stage of our model has three cone types, with L:M:S cones in ratios of 10:5:1. In the second stage, retinal connectivity leads to three pairs of cone-opponent, and one pair of cone-nonopponent systems. At a third (cortical) stage of color processing, the S-opponent cells are added to or subtracted from the L- and M-opponent units to split and

Edge Coloring Models as Singular Vertex Coloring Models
2010In this paper we study an interesting class of graph parameters. These parameters arise both from edge coloring models and from limits of vertex coloring models with a fixed number of vertices. Their vertex connection matrices have exponentially bounded rank growth.

Ocean color is determined by spectral variations in reflectance at the sea surface. In the analytic model presented here, reflectance at the sea surface is estimated with the quasi-single-scattering approximation that ignores transspectral processes. The analytic solutions we obtained are valid for a vertically homogeneous water column.
