Definitions for "Dithering"
A technique used to fill the gap between two pixels with a further pixel in order to smooth out the value of the two or add further detail.
the attempt by a computer program to approximate a color from a mixture of other colors when the required color is not available.
Simulation of a color by grouping pixels of other colors. The human eye sees the grouped pixels as a mixed color. Dithering is useful when not enough colors are available on the monitor to exactly match a color in an illustration.
When a digital audio signal is transmitted to a device with a lower quantization (*see entry), dithering combines some of the rounded-off portion with the data that is retained (i.e., instead of simply discarding the lower-value bits), in order to reduce the noise that is generated by this conversion. Since this changes the data itself, there are situations in which it is better not to apply dithering.
The introduction of digital noise. This is the process the DoD uses to add inaccuracy to GPS signals to induce Selective Availability.
An introduction of digital noise. The Department of Defense's process to add inaccuracy to GPS signals to induce Selective Availability.
