What is dithering technique?

In computer graphics, dithering is an image processing operation used to create the illusion of color depth in images with a limited color palette. Colors not available in the palette are approximated by a diffusion of colored pixels from within the available palette.

What is dithering in images?

Dithering is the process of defining gradations of gray or color shades in a 2-D graphic by varying the gray or color shades in the neighboring pixels.

What is dither signal?

Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of mastering audio to a CD.

What is dithering in video?

Dithering is a technique you can use to make a lower bit-depth blend colors by introducing random noise to the image in strategic locations. When is dithering useful? - When you need to represent an image with lower bit depth than you captured it at, or when you need to use a low bit depth in general.
