Why do some colors look special? Color vision is our ability to distinguish the spectral characteristics of light. Wavelength varies continuously, yet we perceive spectra in terms of a small number of dimensions anchored by salient landmarks. These dimensions define a color space, within which colors appear to vary in hue (direction) or saturation (distance) relative to a neutral gray (Figure 1...

Thank you for downloading the structure and properties of color spaces and the representation of color images synthesis lect. As you may know, people have search hundreds times for their chosen books like this the structure and properties of color spaces and the representation of color images synthesis lect, but end up in infectious downloads. Rather than enjoying a good book with a cup of tea ...

OBJECTIVES As computing technology and image analysis techniques have advanced, the practice of histology has grown from a purely qualitative method to one that is highly quantified. Current image analysis software is imprecise and prone to wide variation due to common artifacts and histological limitations. In order to minimize the impact of these artifacts, a more robust method for quantitati...

The ability to associate labels to colors is very natural for human beings. Though, this apparently simple task hides very complex and still unsolved problems, spreading over many different disciplines ranging from neurophysiology to psychology and imaging. In this paper, we propose a discrete model for computational color categorization and naming. Starting from the 424 color specimens of the ...

Breast-conserving therapy/Breast cancer/Radiation dermatitis. The purpose of this study was to evaluate the significance of skin phototype (suntan or sunburn type) in association with radiation dermatitis in patients with breast cancer who underwent postoperative radiotherapy after breast-conserving surgery because phototype could predict sunlight reaction. We divided patients into two phototyp...

Perceptual image distortion measures can play a fundamental role in evaluating and optimizing imaging systems and image processing algorithms. Many existing measures are formulated to represent “just noticeable differences” (JNDs), as measured in psychophysical experiments on human subjects. But some image distortions, such as those arising from small changes in the intensity of the ambient ill...

Paintings are made up of materials that can suffer damage with the passage of time. To protect them over a long period, they are coated with a protecting covering of varnish layer. The varnish layer over paintings is affected by atmospheric conditions, fluctuations in temperatures, humidity and sunlight. Over a period of time, the transparency of the varnish becomes clouded and discolored, ofte...

The paper presents a statistical evaluation of the typological data about color naming systems across the languages of the world that have been obtained by the World Color Survey. In a first step, we discuss a singular value decomposition of the categorization data that led to a small set of easily interpretable features dominant in color categorization. These features were used for a dimension...

The problem of the design of color scanning filters is addressed in this paper. The problem is posed within the framework of the vector space approach to color systems. The measure of the goodness of a set of color scanning filters presented in earlier work is used as an optimization criterion to design color scanning filters modeled in terms of known, smooth, nonnegative functions. The best fi...

Studying color preferences provides a means to discover how perceptual experiences map onto cognitive and affective judgments. A challenge is finding a parsimonious way to describe and predict patterns of color preferences, which are complex with rich individual differences. One approach has been to model color preferences using factors from metric color spaces to establish direct correspondenc...
