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.

在中国市场,这一转型呈现出更为复杂的现实图景。一方面,继续依赖抽佣,短期内仍可能支撑财务表现;但长期看,生态摩擦加剧、供给侧对抗与用户体验下降,将反过来侵蚀平台的商业基础。另一方面,转向服务化、工具化与效率定价,虽然短期承压,却有助于重建平台与供给侧之间的关系,使平台从分配者逐步转向基础设施提供者。,更多细节参见WPS下载最新地址
