A New Method for Quantifying Colour Rendering
نویسندگان
چکیده
This paper is aimed to develop some new measures for quantifying colour rendering between a reference and a test illuminant. In addition, CIE colour rendering index (CRI) and Colour Quality Scale (CQS) were evaluated using different sets of testing samples in order to reveal whether the two measures are sample dependent or not.

Metamer Mismatching as a Measure of the Color Rendering of Lights
We propose a new method for evaluating the colour rendering properties of lights. The proposed method uses the degree of metamer mismatching for flat grey (constant reflectance of 0.5) quantified in terms of the metamer mismatch volume index proposed by Logvinenko et al. . The standard CIE color rendering index (CRI) [1] has been widely criticized, especially when evaluating LEDs. One of the ke...
متن کاملThe Concept of Colour Rendering Revisited
The currently used colour rendering index is based on an outdated colour space and chromatic adaptation formula. The perceived and calculated colour rendering of new light sources shows discrepancies. This becomes acute with the introduction of LED sources and increased use of coloured samples produced by ink-jet printers and colour-photocopy. Recent colour appearance models enable an advanced ...
متن کاملSpectral Volume Rendering
We describe a method for volume rendering using a spectral representation of colour instead of RGB. Full spectra allow the generation of physically correct rendering of a scene under different lighting conditions. To make the method practicable, a new low-dimension subspace method is used to act as the carrier of spectral information. To fully exploit spectra, we introduce the technique of post...
متن کاملEnergy Aware Colour Mapping for Visualization
We present a design technique for colours that lower the energy consumption of the display device. Our approach relies on a screen space variant energy model. Guided by perceptual principles, we present three variations of our approach for finding low energy, distinguishable, iso-lightness colours. The first is based on a set of discrete user-named (categorical) colours, which are ordered accor...
متن کاملQuantifying Plant Colour and Colour Difference as Perceived by Humans Using Digital Images
Human perception of plant leaf and flower colour can influence species management. Colour and colour contrast may influence the detectability of invasive or rare species during surveys. Quantitative, repeatable measures of plant colour are required for comparison across studies and generalisation across species. We present a standard method for measuring plant leaf and flower colour traits usin...
