Did you know?
WebOrdered dithering is an image dithering algorithm. It is commonly used by programs that need to provide continuous image of higher colors on a display of less color depth. For example, Microsoft Windows uses it in 16-color graphics modes. It is easily distinguished by its noticeable crosshatch patterns.

The randomness of the noise mask is replaced by a fixed, repeated pattern. However, clustering the “on” pixels in this way creates strong artefacts (the dots!) that are not necessary for electronic displays.
WebImplement the Ordered Dithering algorithm, explained in the slides, in a Matlab function that takes an image and the dithering matrix as input parameters and returns the dithered image.

WebApr 13, 2024 · BayerMatrix. A simple algorithm to generate bayer matrix for ordered dithering. Can output to PNG using PIL. The PNG files included in this repo should be enough for most use cases. For dithering, the 16x16 version should produce the best results with the least banding since it has 256 discrete values as opposed to 64 in the 8x8 version.
WebMay 14, 2024 · Dordered = orddither (inpict,16,'color'); This isn't the method used by rgb2ind () with the 'dither' flag. That requires color quantization and it requires the index assignment to be incorporated into the error diffusion process.
