What is Dither?
{{Orphan|date=December 2010}} '''Dithering''' is the intentional use of [[noise]] (random sounds) to reduce the error of compression. Example below: {{Image gallery |lines=6 |width=260 |File:Dithering example undithered.png|Figure 1. Original photo; note the smoothness in the detail. |File:Dithering example undithered web palette.png|Figure 2. Original image using the web-safe color palette with no dithering applied. Note the large flat areas and loss of detail. |File:Dithering example dithered web palette.png|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. |File:Dithering example dithered 256color.png|Figure 4. Here, the original has been reduced to a 256-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. |File:Dithering example undithered 16color.png|Figure 5. Depth is reduced to a 16-color optimized palette in this image, with no dithering. Colors appear muted, and color banding is pronounced. |File:Dithering example dithered 16color.png|Figure 6. This image also uses the 16-color optimized palette, but the use of dithering helps to reduce banding. }} [[Category:Digital signal processing]] [[Category:Computer graphics]] [[Category:Sound]] {{tech-stub}}
