(Bilgisayar) dithering
A technique used in computer graphics to create the illusion of varying shades of gray or additional colors by distributing the screen pixels or imagesetter dots of an image Dithering relies on the eye's tendency to blur spots of different colors by averaging their effects and merging them into a single perceived shade or color
Dithering is the approximation of a colour by the visual mixing of adjacent pixels of a similar colour used in producing acceptable images based on a limited colour range Pixels are automatically arranged in such a way as to fool the human eye Without dithering techniques many bitmap images would look harsh with jagged edges when the available colour palette is restricted to 256 colours or less
A technique for mixing two or more colours together in a dot pattern to create the illusion of additional colours
present participle of dither
a display technique that is used in ERDAS IMAGINE to allow a smaller set of colors appear to be a larger set of colors
Dithering is a method of simulating full-colour images on a 256-colour computer display Pixels from the 256-colour palette are combined into patterns that approximate other colours The human eye merges these patterns into a single combined colour when viewed at a distance Dithering can increase the size of GIF images as it increases the likelihood of increasing the horizontal variation in such images The use of the 216 colour Netscape palette (the non-dithering, browser default palette) avoids dithering If necessary, this palette can be translated into either an adaptive or optimized palette for further colour reduction
To approximate a color from a mixture of other colors when the required color is not available For example, pink can be approximated by placing red pixels adjacent to white pixels
Dithering is a common technique to improve digitizing when quantization noise (see also Quantization Error/Noise) can no longer be treated as random This happens when an analog input signal remains at the same value for many consecutive samples, causing the digitized output to look "stuck" at a certain digital output code even when the input is changing by less than ±0 5LSB The quantization noise now looks more like a threshold or a distortion rather than additive random noise To get around this effect, a small amount of random noise is added to the analog input signal This added noise causes the digital output to randomly toggle between two adjacent codes, thereby avoiding the previously described thresholding effect
A technique for alternating the values of adjacent dots or pixels to create the effect of intermediate values In printing color images or displaying color on a computer screen, dithering refers to the technique of making different colors of adjacent dots or pixels give the illusion of a third color; for example, a printed field of alternating cyan and yellow dots appears to be green Dithering can give the effect of shades of gray on a black-and-white display or the effect of more colors on a color display
A technique that is used to add more colors or shades of gray to an existing image, the goal being to improve the appearance of the image Can be thought of as the inverse to quantization
A technique for creating an image with apparent levels of gray by grouping black and white dots into cells According to the number of black and white dots and their arrangement in the cell, the eye perceives the cell as a single gray, not as a group of black and white dots Commonly used by laser printers to simulate grey images The NDLP use of diffuse dithering represents a special case in which the scanner's dot pattern is randomized
One of many processes for reducing the total number of colors present in an image while retaining visual fidelity Dithering can be done by interleaving pixels of selected colors to locally approximate the desired color Dithering can be applied to either a color or a greyscale color space and may be necessary due to a limited number of colors available on the display device
When a color that is not browser safe is displayed, two browser safe colors are mixed (or alternated) to create the desired color This is called dithering
A process which gives the illusion of varying shades of gray or shades of color
{i} mixing of colors, blending of pixels of different colors in order to create an area of intermediate color (Computers)
Dithering occurs when a Web browser attempts to display colors that are not in its native color palette, by placing close together pixels in colors that the computer can display The results are generally unattractive, as seen below
A method of displaying colours that are not available on a printer/monitor etc The illusions of created by mixing available colours
A process by which computers approximate the display of colors in an image that are not available given the particular system configuration Dithering is achieved by varying the patterns of dots that make up the image Dithering slows down the display of graphics, so using colors that are available on as many systems as possible improves the performance of web pages that include graphics E
(n ) The process of simulating unavailable colors in a displayed graphic by using a pattern of two or more available colors
When working with a computer display system that supports 8-bit color (or less), the video card can display only 256 different colors at one time Dithering is a technique to simulate the display of colors that are not in the current color palette of a particular image It accomplishes this by arranging adjacent pixels of different colors into a pattern which simulates colors that are not available to the computer
