Comparison of Imaging Models for Spectral Unmixing in Oil Painting

Sensors, 2021
The radiation captured in spectral imaging depends on both the complex light–matter interaction and the integration of the radiant light by the imaging system.

Colour Spaces for Colour Transfer [PDF]

, 2011
Colour transfer algorithms aim to apply a colour palette, mood or style from one image to another, operating either in a threedimensional colour space, or splitting the problem into three simpler one-dimensional problems. The latter class of algorithms simply treats each of the three dimensions independently, whether justified or not.

Assessment of Camouflage Effectiveness Based on Perceived Color Difference and Gradient Magnitude

Sensors, 2020
We propose a new model to assess the effectiveness of camouflage in terms of perceived color difference and gradient magnitude. The “image color similarity index” (ICSI) and gradient magnitude similarity deviation (GMSD) were employed to analyze color ...

Reduction of the Number of Samples for Cost-Effective Hyperspectral Grape Quality Predictive Models

Foods, 2021
Developing chemometric models from near-infrared (NIR) spectra requires the use of a representative calibration set of the entire population. Therefore, generally, the calibration procedure requires a large number of resources.

A test of the ecological valence theory of color preference, the case of Arabic

Frontiers in Psychology, 2022
Humans have systematic and reliable color preferences. The dominant account of color preference is that individuals like some colors more than others due to the valence of objects that they associate with colors (Ecological Valence Theory). In support of

The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

A Study of Overripe Seed Byproducts from Sun-Dried Grapes by Dispersive Raman Spectroscopy

Foods, 2021
Overripe seeds from sun-dried grapes submitted to postharvest dehydration constitute a scarcely investigated class of vinification byproduct with limited reports on their phenolic composition and industrial applications. In this study, Raman spectroscopy

Colour calculus and colour quantizations [PDF]

Acta Applicandae Mathematicae, 1995
Let \(A\) be an associative algebra over a commutative field \(k\), let \(\lambda \in \Aut A\). Then a \(\lambda\)-derivation of the algebra \(A\) is defined to be a \(k\)-linear map \( X_\lambda : A \to A\) such that the Leibniz rule holds in the following version: \(X_\lambda (ab) = X_\lambda a \cdot b + \lambda (a) \cdot X_\lambda b\). In section 1,
