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 :
习近平总书记深情地说：“衡量干部业绩好不好，关键要看老百姓口碑好不好。各级领导干部要向谷文昌同志学习，树牢正确政绩观，为官一任、造福一方，真抓实干、久久为功，把丰碑立在人民群众心中。”
