Another way to look at our threshold matrix is as a kind of probability matrix. Instead of offsetting the input pixel by the value given in the threshold matrix, we can instead use the value to sample from the cumulative probability of possible candidate colours, where each colour is assigned a probability or weight . Each colour’s weight represents it’s proportional contribution to the input colour. Colours with greater weight are then more likely to be picked for a given pixel and vice-versa, such that the local average for a given region should converge to that of the original input value. We can call this the N-candidate approach to palette dithering.，这一点在新收录的资料中也有详细论述

清华大学无障碍发展研究院院长邵磊认为，无障碍设施建设不规范、动线不畅通、管理不到位，表面上是某个“点位”的问题，实则是无障碍环境和服务系统性不足。“在现实中，无论是公共还是私人领域，我们会经常遇到责任主体不明确甚至互相推诿、协调权能不够，或者缺乏资金等状况，导致无障碍系统出现漏洞。”邵磊说。
