The transformation of the RGB colour space to a hue, saturation and brightness colour space is essentially a conversion from a rectangular coordinate system to a cylindrical coordinate system. Nevertheless, a bewildering array of such conversions exist. We show that one of the main reasons for this is the dependence of the saturation values on the choice of the brightness function, and suggest ...

For multiprimary displays, color within the interior of the gamut can be reproduced with several different control values, a situation that is in contrast with the three primary scenario, where the control values are unique. For a given color, the selection of the control values, or color calibration, becomes a fundamental step for color rendition on multiprimary devices. Because spatially smoo...

introduction: the use of computer vision technology has been highly successful in food classification in the past and it has continued this success in recent times. however, a number of opportunities to progress computer vision technology exist which are critically examined based on cost and feasibility. a range of hardware options are considered along with a range of software options. the econ...

We propose a novel method to analyze a sequence of color images. A series of color images is examined in a four-dimensional space, which we call the temporal-color space, whose axes are the three color axes red, green, and blue and one temporal axis. The significance of the temporal-color space lies in its ability to represent the change of image color with time. A conventional color space anal...

We present a method to give (fused) multiband night-time imagery a natural day-time colour appearance. For input, the method requires a false colour RGB image that is produced by mapping three individual bands (or the first three principal components) of a multiband nightvision system to the respective channels of an RGB image. The false colour RGB nightvision image is transformed into a percep...

Human perception of colors constitutes an important part in color theory. The applications of color science are truly omnipresent, and what impression colors make on human plays vital role in them. In this paper we offer the novel approach for color information representation and processing using fuzzy sets and logic theory, which is extremely useful in modeling human impressions. Specifically,...
