The pruned nodes (in red) represent entire regions of space that the algorithm never examines. The points inside those regions are never checked. Compare the "Nodes Visited" count to the total number of points. The quadtree is doing far less work than a brute-force scan.
2012年，旧国标《环境空气质量标准》（GB 3095—2012）修订发布，首次纳入PM2.5限值，堪称中国大气污染治理的里程碑之一。李天威称，在生态环境领域2400多项环境标准中，《环境空气质量标准》是其中唯一经过国务院常务会议部署修订发布的。

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.
