Single-photon emitters with stable and uniform photoluminescence properties are important for quantum technology. However, in many cases, colour centres in diamond exhibit spectral diffusion and photoluminescence intensity fluctuation. It is therefore essential to investigate the dynamics of colour centres at the single defect level in order to enable the on-demand manipulation and improved app...

A pixel-level fusion technique for RGB representation of multispectral images is proposed. The technique results in highly correlated RGB components, a fact which occurs in natural colour images and is strictly related to the colour perception attributes of the human eye. Accordingly, specific properties for the covariance matrix of the final RGB image are demanded. Mutual information is employ...

Sažetak A study of physico-chemical properties and instrumental measurement of colour and texture was carried out on seven different brands of traditional homemade dry fermented horse salami from Pakrac area. Basic physico-chemical properties, pH values and salt content showed significant variability (p = 0.05), except for the values of aw. Textural and colour parameters (L*, a* and b*) also sh...

During the last decade it has become clear that colour vision in platyrrhines (New World monkeys) differs from the uniform trichromatic pattern normally found in catarrhines (Old World monkeys, apes and human). Colour vision in most platyrrhine species is polymorphic, with many dichromatic individuals. The comparison of response properties in retinal ganglion cells and lateral geniculate cells ...

Electrochromic materials have the possibility to change their colour reversibly when they are transformed in a differently charged state. By applying an external voltage, charged molecules move towards the electrodes where they accept or donate an electron, and obtain a different colour. When the external voltage is switched off, they return to their initial colour. Recently electrochromism has...

Fruit ripening and softening indicated by firmness determines the texture transportability, shelf life of tomato products. However, regulatory mechanism underlying formation in is different varieties overall fruit poorly understood. Therefore, this study, physical, biochemical, molecular properties three varieties; ‘Sarikiz’ (yellow skin colour), ‘Moda’ (orange colour) ‘Red Type Cherry’ (red at...

Colour is an increasingly common feature of computer workstations. New ideas, algorithms and knowledge are needed to harmonize the user's desire for improved aesthetic appeal and the programmer's desire for an interface of greater functionality. This paper discusses several areas in which colour leads to novel functionality, visual search , grouping by colour and colour coding. The current obst...

With the development of autonomous underwater vehicles, the identification of underwater objects continues as a major issue. Because of specific properties of light in water particularly the absorption phenomenon, underwater imaging suffers from low contrast, from diminished colours and often from prominent green or blue colour. Today, object identification algorithms are usually based on shape...

We investigate the radial colour gradient and two-dimensional (2D) colour properties of 22 E+A galaxies with 5.5Å < Hδ EW < 8.5Å and 49 normal early-type galaxies as a control sample at a redshift of < 0.2 in the Second Data Release of the Sloan Digital Sky Survey. We found that a substantial number of E+A galaxies exhibit positive slopes of radial colour gradient (bluer gradients toward the ce...
