Error diffusion is a type of halftoning in which the quantization residual is distributed to neighboring pixels that have not yet been processed. Its main use is to convert a multi-level image into a binary image, though it has other applications. Unlike many other halftoning methods, error diffusion is classified as an area operation, because what the algorithm does at one location influences what happens at other locations. This means buffering is required, and complicates parallel processing. Point operations, such as ordered dither , do not have these complications.

Continuous tone images must be halftoned to be displayed on binary output devices such as printers. The ordered dither algorithm is a popular approach to halftoning. This algorithm uses a threshold matrix to approximate gray scale values.

Nilsson, "Halftoning and objective quality measures for halftoned images," Linkoping Studies in Science and. Introduction Halftoning refers to converting a continuous-tone image into a pattern of black and white dots [Uli87]. The key factors for the quality of halftoning are the precise preservation of both tone and structure from the original image, and the absence of spurious patterns. In order to form patterns a valid reaction-diffusion system must exhibit local instability to small random per-turbations. That notwithstanding, the system should be stable in the large-signal sense for practical reasons. A major difficulty associated with the reaction-diffusion paradigm in its standard form is that the system is stable only for a.

 - Не желаете купить. Нуматака чуть не расхохотался во весь голос. Он знал, что это трюк. Корпорация Нуматек сделала очень крупную ставку на новый алгоритм Танкадо, и теперь кто-то из конкурентов пытается выведать ее величину. - У вас есть ключ? - сказал Нуматака с деланным интересом.

 Все когда-то бывает в первый раз, - бесстрастно ответил Бринкерхофф. Она встретила эти слова с явным неодобрением.

 Дэвид, - вздохнула она, заметив на тумбочке его записку.  - Скажи мне, что такое без воска. Ты же знаешь, что шифры, которые не поддаются, не выходят у меня из головы.

Мидж не поддалась. - Прими аспирин. - Не помассируешь мне спину? - Он надулся. Мидж покачала головой. - В Космополитене пишут, что две трети просьб потереть спинку кончаются сексом.
