In the present study, the authors explore in detail the level of visual object recognition at which perceptual color information improves the recognition of color diagnostic and noncolor diagnostic objects. To address this issue, 3 object recognition tasks with different cognitive demands were designed: (a) an object verification task; (b) a category verification task; and (c) a name verificati...

Although basic color terms and basic color appearances have been shown to produce higher confidence ratings in a variety of naming and judgment tasks, our findings suggest that when different ethnolinguistic cultures are compared, higher confidence is not strictly linked to the basic foci of Berlin and Kay nor the centroid samples identified by Boynton and colleagues. This raises important ques...

I argue against a class of philosophical views of color perception, especially insofar as such views posit the existence of color sensations. I argue against the need to posit such nonconceptual mental intermediaries between the stimulus and the eventual conceptualized perceptual judgment. Central to my arguments are considerations of certain color illusions. Such illusions are best explained b...

A substantial body of scholarship on men of color in postsecondary education has emerged since the late 1990s. Yet, only recently have scholars begun to pursue empirical insights about the status of men of color who attend community colleges. In an effort to inform future research, this article reviews the published scholarship on student success for men of color in community colleges. The 5 do...

Video processing is generally concerned with color represented in three components derived from the scene, usually red, green, and blue or components computed from these. Once red, green, and blue components of a scene are obtained, color coding systems transform these components into other forms suitable for processing, recording, and transmission. Accurate color reproduction depends on knowle...

In the field of outdoor scene analysis [1], well known procedure to analyze an image is as follows: (1) The image is divided into regions mainly based on color feature. (2) Each region is hypothesized as an object based on statistical knowledge between its characteristics and object labels. (3) The hypotheses are checked by knowledge of three dimensional relation among the objects. In theses st...

According to predictive coding models of perception, what we see is determined jointly by the current input and the priors established by previous experience, expectations, and other contextual factors. The same input can thus be perceived differently depending on the priors that are brought to bear during viewing. Here, I show that expected (diagnostic) colors are perceived more vividly than a...

Human visual system has the property of perceiving the object color to remain constant regardless of the prevailing illumination. However, digital cameras usually lack this capability, and the captured images are digitally corrected to discount the color of the scene light based on the estimated illuminant. Illumination estimation might be erroneous in some artificial or chromatic lighting cond...
