CRT MONITOR cathode-ray tube



Disadvantages of CRT

They have a big back and take up space on desk.
The electromagnetic fields emitted by CRT monitors constitute a health hazard to the functioning of living cells.
CRTs emit a small amount of X-ray band radiation which can result in a health hazard.
Constant refreshing of CRT monitors can result in headache.
CRTs operate at very high voltage which can overheat system or result in an implosion
Within a CRT a strong vacuum exists in it ....etc

RT stands for cathode ray tube, the common picture tube used in TV sets for decades and still the most common display type today. Newer display types like Plasma and LCD work differently and aren't as large or heavy as the CRT, but the picture isn't necessarily any better.

CRT produces its pictures from a ray of electrons emanating from a cathode in the neck of a picture tube. The ray strikes the inner face of the picture tube, which is coated with lines of phosphor that light up when struck by the electron beam. The scan line offers resolut ....etc

Abstract
Color constancy is the skill by which it is possible to tell the color of an object even under a colored light. I inter-
pret the color of an object as its color under a fixed canonical light, rather than as a surface reflectance function.
This leads to an analysis that shows two distinct sets of circumstances under which color constancy is possible.
In this framework, color constancy requires estimating the illuminant under which the image was taken. The estimate
is then used to choose one of a set of linear maps, which is appli ....etc

We have done a detailed analysis of the visual properties of the HSV (Hue, Saturation and Intensity Value) color space and Human visual system. Using the results of these analyses, we determine relative importance of hue and intensity based on the saturation of an image pixel with respect to rod and cone cells excitation of retina. We effectively apply this method to the generation of a color histogram and use it for content-based image retrieval applications. A web-based system has been developed for demonstrating our work ....etc

This paper presents a zero tree coding method for color images that uses no lists during encoding and decoding,permitting the omission of the lists requirement in Said and Pearlman's Set Partitioning In Hierarchical Trees (SPIHT) algorithm . Without the lists, the memory requirement in a VLSI implementation is reduced significantly. This coding algorithm is also developed to reduce the circuit complexity of an implementation. Our experimental results show only a minor reduction of PSNR values when compared with the PSNR values obtained by th ....etc
