Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
算法为数字纪检监察体系提供“智慧核心”。有了海量数据，还需要科学算法挖掘其内在价值。有了科学算法，数字纪检监察体系就有了从纷繁复杂的数据里寻线索、找规律、揪异常的“火眼金睛”。比如，通过整合干部的岗位信息、履职轨迹、廉政记录，可以搭建起廉洁风险评估模型，及时发现苗头性、倾向性问题；通过关联分析项目审批、招标文件、资金流向等数据，能让新型腐败、隐性腐败无处遁形。

Was that really Peter Mandelson getting into a police car on Monday? Was it really the same Mandelson who had supposedly been about to flee to the British Virgin Islands, the man called “a traitor” to his country and the buddy of a sex trafficker of girls? Was he really to be questioned for nine hours by the police over “misconduct in public office”, an offence few people have ever heard of? For a moment, I thought it must be a trailer for a new Epstein docudrama “inspired by real-life events”.
