The talk will present results of a statistical evaluation of the data from the World Color Survey, a large scale typological questionnaire study on the lexical semantics of basic color terms. Unlike most previous studies on the topic, I mainly use data from individual speakers, rather than generalizations over individual languages, as basis for statistical inference. I will present two main fin...

Day vision and night vision are two separate modes of visual perception and the visual system shifts from one mode to the other based on ambient light levels. Each mode is primarily mediated by one of two photoreceptor classes in the retina, i.e., cones and rods. In day vision, visual perception is primarily cone-mediated and perceptions are chromatic. In other words, color vision is present in...

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...

Average relative color preferences for a given sample of colors are typically measured behaviorally by asking a group of people to perform one of three tasks. First, the observers can be asked to indicate which of two simultaneously presented colors they prefer for each possible pair of colors in the sample. The probability, averaged over observers, of choosing each color versus all other sampl...

In Computer Vision, the sky color is used for lighting correction, image color enhancement, horizon alignment, image indexing, and outdoor image classification and in many other applications. In this article, for robust color based sky segmentation and detection, usage of lighting correction for sky color detection is investigated. As such, the impact of color constancy on sky color detection a...
