Diffusion dithering
WebIn particular, we propose a Conditional Diffusion model for image Halftoning (CDH), which consists of a halftone dithering process and an inverse halftoning process. By changing the initial state of the diffusion model, our method can generate visually plausible halftones with different dithering patterns under the condition of image gray level ... The algorithm achieves dithering using error diffusion, meaning it pushes (adds) the residual quantization error of a pixel onto its neighboring pixels, to be dealt with later. It spreads the debt out according to the distribution (shown as a map of the neighboring pixels): The pixel indicated with a star (*) indicates the pixel currently being scanned, and the blank pixels are the previously-scanned pixels. The algorithm scans the image from left to right, top to botto…

WebAug 15, 2012 · You can set the dither mode by going to Edit > Preferences, but the mode you select will only be applied to images that are added after the preference was selected. There are 6 dither mode choices and one non-dithering mode. Some modes will work very well for a certain photo and terrible for others, so you may need to choose a different … Error-diffusion dithering (continued): Sierra dithering is based on Jarvis dithering, but it's faster while giving similar results. Two-row Sierra is the above method, but was modified by Sierra to improve its speed. Filter Lite is an algorithm by Sierra that is much simpler and faster than Floyd–Steinberg, while still yielding … See more Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images.
