古胥河畔，南京高淳“东坝大马灯”的表演好不热闹。7个娃娃身骑“竹马”，扮上花脸，衣着戏袍：绿衣是关羽，黑脸的是张飞，骑白马的是赵云……7匹“竹马”之下，各有两名成年人默契配合，前一人戴道具扮马头，后一人屈身披锦作马身，演绎战马的静立和奔腾。令旗所指，摆出三角阵、四角阵、梅花阵……
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.
And conversely, if I want to revert the modifications, that’s also possible:
