Three kinds of silicate phosphor thin films, emitting in the red-green-blue (RGB) primary colors, were fabricated by pulsed laser deposition: manganese and lead doped calcium silicate (CaSiO3:MnPb) for red color, manganese doped zinc silicate (Zn2SiO4:Mn) for green color, and cerium doped yttrium silicate (Y2SiO5:Ce) for blue color. A good correlation was found between photoluminescence intensi...
BACKGROUND People with color vision deficiencies report numerous limitations in daily life, restricting, for example, their access to some professions. However, they use basic color terms systematically and in a similar manner as people with normal color vision. We hypothesize that a possible explanation for this discrepancy between color perception and behavioral consequences might be found in...
Fruit color is an important economic trait. The color of red walnut cultivars is mainly attributed to anthocyanins. The aim of this study was to explore the differences in the molecular mechanism of leaf and peel color change between red and green walnut. A reference transcriptome of walnut was sequenced and annotated to identify genes related to fruit color at the ripening stage. More than 290...
A huge set of focused attention experiments show that when presented with color words printed in color, observers report the ink color faster if the carrier word is the name of the color rather than the name of an alternative color, the Stroop effect. There is also a large number (although not so numerous as the Stroop task) of so-called "redundant targets studies" that are based on divided att...
In purchasing fresh retail meat, the microbiological shelf life, color and general appearance are important features to the consumers. Underlying these features, food safety and product confidence has been increasingly emphasized. Growth of spoilage and pathogenic bacteria is generally reduced by stringent hygienic standards, low storage temperatures and by using modified atmospheres packaging ...
Measurements of contrast sensitivity are well established for modulations in luminance, red-green and yellow-blue color directions in color space. Relatively less work has been carried out, however, to measure contrast sensitivity in other color directions or to assess the effect of the average color of the stimulus has been largely ignored. In this study we have measured conventional contrast-...
Demosaicking and zooming are important for the quality of digital images in resource-constrained single chip devices such as wireless camera phones and vision-based pocket devices. The color artifacts introduced in the demosaicking process can be magnified in the subsequent zooming process and vice versa. This paper presents a joint demosaicking–zooming scheme by exploiting the fact that red/gr...
Recent theories propose that language comprehension can influence perception at the low level of perceptual system. Here, we used an adaptation paradigm to test whether processing language caused color adaptation in the visual system. After prolonged exposure to a color linguistic context, which depicted red, green, or non-specific color scenes, participants immediately performed a color detect...
Light sources with three spectral bands in specific spectral positions are known to have high-color-discrimination capability. W. A. Thornton hypothesized that they may also enhance color discrimination for color-deficient observers. This hypothesis was tested here by comparing the Rösch-MacAdam color volume for color-deficient observers rendered by three of these singular spectra, two reported...
