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.

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.

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

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,

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

THE DISCRIMINATION OF COLOUR [PDF]
BMJ, 1911 Abstract In a paper on the relation of light perception to colour perception, and in previous writings, I have stated that if a portion of the spectrum be isolated, it will appear monochromatic, the length of the monochromatic region varying with the intensity and wave-length of the light and the colour perception of the observer ...

The effect of new LED lighting systems on the colour of modern paints
Scientific Reports, 2021 This research focuses on the investigation of the effect of a new light emitting diode (LED)-lighting system which reproduces indoor museum conditions, on some self-made art paint colours (acrylic-, alkyd-, and linseed oil-based paints) often used in ...
