RGB colors

At each image point, we only measure three values. We obtain the intensities from the sensor in the red, green, and blue part of the spectrum. This leads to the RGB color... 

Color in the HSI color space is represented as three components hue, saturation, and intensity (Gonzalez and Woods 1992 Jain et al. 1995 Smith 1978). Any point in the RGB color space can also be specified using the HSI color model. The attribute hue defines the color of the point. Saturation specifies the amount of white added to the pure color. Finally, intensity specifies the brightness of the point. It is not clear if the HSI components are defined for linear RGB or nonlinear RGB space (Poynton 1997, 1998). Therefore, it is not possible to determine whether the components of the HSI color space refer to a physical...

Figure 7.29 A circle of colors in RGB color space is shown in (a). When we transform data points that are sampled along the circle to log-chromaticity difference space, we obtain the graph in (b).

Figure 8.3 Algorithm of Pomierski and GroB (1995). (a) A cloud of points inside the RGB color cube. The main axis is also shown, (b) The cloud of points is rotated onto the gray vector, (c) The point cloud is rescaled such that the color space is completely filled.

Let us now have a different look on the use of local space average color for color constancy using color shifts. Consider the standard RGB color space. A unit cube is spanned by the...

Another major technology area that can utflize conductive IJ ink is the display market. Inkjet can be applied for both flexible and rigid displays such as electroluminescent and electrophoretic displays (including e-paper), hquid crystal displays (LCD), plasma display panels (PDP) and touch screens some functionalities have already been printed by IJ technology in certain display apphcations, for example RGB color filters. Conductive IJ is also appropriate for use in thin film transistors (TFT), disposable batteries, radio-frequency identification (RFID) tags, and a range of chemical and electronic sensors. 

Next the designer translates each FR into a corresponding set of DPs in the physical domain. These DPs are your critical material/service targets and specifications. For instance, if the FR is to make a part blue in color, then the DP for that FR might be to target 0/0/255 (blue) on the RGB color scale, with a tolerance of plus or minus five points on the RGB scale. 

The realization of red-green-blue (RGB) color dots (pixels) building up a color flat-panel display (CFPD)-based polymer LEDs can be achieved via several techniques 56...
