Another way to approach dithering is to analyse the input image in order to make informed decisions about how best to perturb pixel values prior to quantisation. Error-diffusion dithering does this by sequentially taking the quantisation error for the current pixel (the difference between the input value and the quantised value) and distributing it to surrounding pixels in variable proportions according to a diffusion kernel . The result is that input pixel values are perturbed just enough to compensate for the error introduced by previous pixels.
数据要素正成为经济社会高质量发展关键动能。从历史演进规律看，每一次划时代的生产力飞跃，均由关键生产要素的革新所驱动，农业文明土地与劳力是核心要素，工业文明依靠资本与技术，而正在蓬勃兴起的数字文明，其核心驱动力正转向数据；从国际格局演变看，数据主权已成为国家综合竞争力的重要体现，直接关系到一国能否在未来全球竞争体系中赢得主动、塑造优势；从国内发展需求看，数据要素已深度融入生产、分配、流通、消费等各环节，正引发生产方式、社会结构和治理模式的重塑，成为突围破局的重要抓手、价值创造的重要源泉、赋能发展的重要动力，对于促进科技协同创新、产业转型升级、区域协调发展、社会精准治理等方面具有“四两拨千斤”的作用。
