If inside, the dither is treated as part of the error signal and shaped along with actual quantization error. If outside, the dither is treated as part of the original signal and linearises quantization without being shaped itself. In this case, the final noise floor is the frse of the flat dither spectrum and the shaped quantization noise.

    While real-world noise shaping usually includes in-loop dithering, it is also possible to use it without adding dither at all, in which case quantization error is evident at low signal levels. Colored dither is sometimes mentioned as dither that has been filtered to be different from white noise. Noise shaping is one such application. If a colored dither is used instead at these intermediate processing stages, then frequency content may " bleed " into other frequency ranges that are more noticeable and become distractingly audible.

    If the signal being dithered is electronic undergo no further processing — if it is being dithered to its final devices for distribution — then a "colored" dither or noise shaping is appropriate. This can effectively lower the audible noise level, by putting most of that noise in a frequency range where it is less critical. Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette.

    In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels download within the available palette. The human eye perceives the diffusion as a mixture of the colors within it see color vision. Dithered images, particularly those using palettes with relatively few colors, can often be distinguished by a characteristic graininess or speckled appearance. Dithering introduces noise or a pattern into an image, and often the patterning is visible.

    In these circumstances, it has been shown that dither generated from blue noise is the least unsightly and distracting. However, other techniques such as ordered dithering can also generate blue-noise dithering without the tendency to degenerate into areas with artifacts. Reducing the color depth of an image can have significant visual side-effects.

    If the original image is a photograph, it is likely to have thousands or even millions of distinct colors. The process of constraining the available colors to a specific color palette effectively throws away a certain amount of color information. A number of factors can free the resulting quality of a color-reduced image. Perhaps most significant is the color palette that will be used in the reduced image. For example, an original image Figure 1 may be reduced to the color web-safe palette.

    If the original pixel colors are simply translated into the closest available color from the palette, no dithering will occur Figure 2. However, typically this approach will result in flat areas contours and a loss of detail and may produce patches of color that are significantly different from the original. Shaded or gradient areas may produce color banding which may be distracting.

    The application of dithering can help to minimize such visual artifacts and usually results in a better representation of the original Figure 3. Dithering helps to reduce floyd banding and flatness. One of the problems associated with using a fixed color palette is that many of the needed colors may not be available in the palette, and many of the available colors may not be needed; a fixed palette containing mostly shades of green would not be well-suited for an image of a desertfor instance.

    The use of an optimized color palette can be of benefit in such cases. An optimized color palette is one in which the available colors are chosen based on how frequently they are used in the original source image. If the image is reduced based on an optimized palette the result is often much closer to the original Figure 4. The number of colors available in the palette is also a contributing factor. If, for example, the palette is limited to only 16 colors then the resulting image could suffer from additional loss of detail, resulting in even more pronounced problems with flatness and color banding Figure 5.

    Once again, dithering can help to minimize such artifacts Figure 6. Figure 2. Original image using the web-safe color palette with no dithering applied. Note the large flat areas and loss of detail. Figure 3. Original image using the web-safe color palette with Floyd—Steinberg dithering. Note that even though the same palette is used, the application of dithering gives a better representation of the original.

    Figure 4. Here, the original has been reduced to a color optimized palette with Floyd—Steinberg dithering applied. The use of an optimized palette, rather than a fixed palette, allows the result to better represent the colors in the original image. Figure 5.


    Depth is reduced to a color optimized palette in this image, with no dithering. Colors appear muted, and color banding is pronounced.

    Figure 6. This image also uses the color optimized palette, but the use of dithering helps to reduce banding. One common application of dithering is to more accurately display graphics containing a greater range of colors than the display hardware is capable of showing. For example, dithering might be used in order to display a photographic image containing millions of colors on video hardware that is only capable of showing colors at a time. The available colors would be used to generate a dithered approximation of the original image.

    Without dithering, the colors in the original image would frwe quantized to the closest available color, resulting in a displayed image that is a poor representation of the original. Some liquid-crystal displays use temporal dithering to achieve a similar effect. Electeonic alternating each pixel's color value rapidly between two approximate colors in the panel's color space, a display panel that natively supports only bit color 6 bits per channel can represent a bit color image 8 bits per channel.

    Dithering such as this, in which the computer's display hardware is the primary limitation on color depthis commonly employed in software such as web browsers. Since a web browser may be retrieving graphical elements from an external source, it may be necessary for the browser to perform dithering on images with too many colors for the available display. It was due to problems with dithering that a color palette known as the " web-safe color palette " was identified, for use in choosing colors that would not be dithered on systems capable of displaying only colors simultaneously.

    The term dither was published in books on analog computation and hydraulically controlled guns shortly after World War II. Though he did not use the term dither, the concept of dithering to reduce quantization patterns was first applied by Lawrence G. Roberts in his MIT master's thesis and article. By dither was being used in the modern sense described in this article.

    But even when the total number of available colors in the display hardware is high enough to properly render full-color digital photographs, banding may still be doenload to the eye, especially in large areas of smooth shade transitions. Modest dithering can resolve this without making the image appear grainy. High-end still image processing software commonly uses these techniques for improved display. Another useful application of dithering is for situations in which the graphics file format elsctronic the limiting factor.

    In particular, the commonly used GIF devices is restricted to the use of or fewer colors. For such situations, graphical editing software may be responsible for dithering images prior to saving them in such restrictive electronic. Dithering is analogous to the halftone technique used in printing. For this download, the term dithering is sometimes used interchangeably with the term halftoningparticularly in association with digital printing. The ability of inkjet printers to print isolated dots has increased the use of dithering in printing.

    A typical desktop inkjet printer can print, at most, just 16 colors as this is the combination of dot or no dot from cyan, magenta, yellow and black print heads. In densely printed areas, where the color is dark the dithering is not always visible because the dots floyd ink merge producing a more uniform print. However, a free inspection of the light areas of a print where dots are further apart reveals dithering patterns.

    There are several algorithms designed to perform dithering. One of the earliest, and still one of the most popular, is the Floyd—Steinberg dithering algorithm, which was developed in One of the strengths of this algorithm is that it minimizes visual artifacts through an error-diffusion process; error-diffusion algorithms typically produce images that more closely represent the original dlectronic simpler dithering algorithms.

    Stimulated Brillouin scattering SBS is a nonlinear optical effect that limits the launched optical power in fiber optic systems. This power limit can be increased by dithering foyd transmit optical center frequency, typically implemented by modulating the laser's bias input. See also devicds scrambling. Phase dithering can be used to improve the quality of the output in direct digital synthesis.

    Another type of temporal dithering has recently been introduced in financial marketsin order to reduce the incentive to engage in high-frequency trading. ParFX, a London foreign exchange market that began trading inimposes brief random delays on all incoming orders; other currency exchanges are reportedly experimenting with the technique. The use of such temporal buffering or dithering has been advocated more broadly in financial frew of equities, commodities, and derivatives.

    1. Harold Devarashetty:

      Originally released on 1 March , on the label Harvest, it built on ideas explored in the band's earlier recordings and live shows, but departs from instrumental thematic by founding member Syd Barrett. The album explores themes including conflict, greed, the passage of time, and mental illness, the latter partly inspired by Barrett's deteriorating mental state.
