Color linear model [PDF]

open access: yes, 1997
In this paper, procedures for creating an effective linear model to represent surface spectra are presented. The model is derived by considering spectral data and the human visual characteristic that depends on wave lengths. Two human visual weighting functions (HVWF) are derived from human visual characteristic. The basis functions of the linear model

Color Representations of Ising Models [PDF]

open access: yesJournal of Theoretical Probability, 2020
AbstractIn Steif and Tykesson (J Prob 16:899–955, 2019), the authors introduced the so-called general divide and color models. One of the best-known examples of such a model is the Ising model with external field $$ h = 0 $$ h = 0 , which ...

Polarized Heavy Quarkonium Production in the Color Evaporation Model

open access: yes, 2017
We explore polarized heavy quarkonium production using the color evaporation model at leading order. We present the polarized to total yield ratio as a function of center of mass energy and rapidity in $p+p$ collisions.

Neugebauer Models for Color Error Diffusion Halftoning

open access: yesJournal of Imaging, 2020
In this paper, we propose a method for halftoning color images based on an error diffusion technique, a color design criterion and Neugebauer models for expressing colors.

The Algebraic Structure of the $gl(n|m)$ Color Calogero-Sutherland Models

open access: yes, 1997
We extend the study on the algebraic structure of the $su(n)$ color Calogero-Sutherland models to the case of $gl(n|m)$ color CS model and show that the generators of the super-Yangian $Y(gl(n|m))$ can be obtained from two $gl(n|m)$ loop algebras.

Evaluation of Color Difference Models for Wide Color Gamut and High Dynamic Range

open access: yesJournal of Imaging
Color difference models (CDMs) are essential for accurate color reproduction in image processing. While CDMs aim to reflect perceived color differences (CDs) from psychophysical data, they remain largely untested in wide color gamut (WCG) and high ...

Skin-color modeling and adaptation [PDF]

open access: yes, 1997
This paper studies a statistical skin-color model and its adaptation. It is revealed that (1) human skin colors cluster in a small region in a color space; (2) the variance of a skin color cluster can be reduced by intensity normalization, and (3) under a certain lighting condition, a skin-color distribution can be characterized by a multivariate ...

A novel color calibration method of multi-spectral camera based on normalized RGB color model

open access: yesResults in Physics, 2020
True-color image of Mars is important for mineral analysis. The working light source of the Mars exploration multi-spectral camera is different from the laboratory calibration light source, so that the commonly used RGB calibration method has a large ...

The clustering of SDSS galaxy groups: mass and color dependence

open access: yes, 2008
We use a sample of galaxy groups selected from the SDSS DR 4 with an adaptive halo-based group finder to probe how the clustering strength of groups depends on their masses and colors.

Modeling human color categorization

open access: yes, 2003
Color matching in Content-Based Image Retrieval is done using a color space and measuring distances between colors. Such an approach yields non-intuitive results for the user. We introduce color categories (or focal colors), determine that they are valid, and use them in two experiments.
