Description
Dithering is a type of half tone thresholding where greyscale (or RGB channel) intensity is converted into a local density of binary pixels. This is ideal for rendering images in devices with a binary output such as printers (greyscale) or with a small number of colours (colour dithering).
The following methods have been implemented (there are several more):
- Floyd-Steinberg
- Atkinson
- Jarvis-Judice-Ninke
- Stucki
- Bayer_2x2
- Bayer_4x4
- Bayer_8x8
- Clustered_4x4
- Random
Here is a good text explaining various dithering algorithm.
