Two experiments with the Stroop paradigm were conducted to investigate the role of phonological codes in access to the meaning of Chinese characters. Subjects named the ink color of viewed characters or color patches. Key items were color characters, their homophones with the same tone, homophones with different tones, and semantic associates. Apart from ®nding the usual Stroop interference eff...

Abstract Color pencil drawing is well-loved due to its rich expressiveness. This paper proposes an approach for generating feature-preserving color drawings from photographs. To mimic the tonal style of drawings, which are much lighter and have relatively lower saturation than photographs, we devise a lightness enhancement mapping reduction mapping. The monotonically decreasing derivative funct...

Enhancing the performance of human face detection, tracking and recognition has been done by skin detection considering it as the fundamental step for the several decades. Of the evolved skin detection techniques, skin cluster classifier based on the human skin tone color are considered along with the concept of combination of two color spaces. This paper presents a novel method of combining mo...

Central cyanosis refers to a bluish discoloration of the skin, lips, tongue, nails, and mucous membranes, and is due to poor arterial oxygenation. Although skin color is one of its characteristic properties, it has long been realized that by the time skin color signs become visible, oxygen saturation is dangerously low. Here we investigate the visibility of cyanosis in light of recent discoveri...

We study the influence of the choice of color space for local tone mapping methods. Many local tone mapping methods do not perform well when applied independently to the three color channels of an RGB image. A common solution is to only treat the luminance channel. However, the question of which color space provides the most suitable luminance definition has not been addressed. The correlation ...

Palettized or indexed color images are the dominant type of image used on the “information super highway.” In spite of this, most image compression algorithms are designed for continuous-tone images. This paper presents a method of loss less ly compressing these palettized images, which treats each color independently. This color-plane method provides substantial compression improvement over ot...

A comprehensive solution set of strategies is proposed for interior color design in this study. Computer aided design methods are utilized to solve the problems in the color scheme process, the existing circumstances, shortage and trend of current color scheme tools are analyzed based on interior design theory and modern design methodology. The appropriative color space is constructd to redound...

In underwater image capturing, color change and presence of haze are the two sources of distortion. These distortions are caused by light scattering and light attenuation occurred by light traveling in water with different wavelengths. These changes are caused by light incident on objects, reflected and deflected by different particles present in the propagation path before reaching the camera....

The color rendition ad hoc team of INCITS W1.1 is working to address issues related to color and tone reproduction for printed output and its perceptual impact on color image quality. The scope of the work includes accuracy of specified colors with emphasis on memory colors, color gamut, and the effective use of tone levels, including issues related to contouring. The team has identified three ...
