I've rounded up the top three TV deals I could find heading into the weekend, with savings up to $1,100. Make note that while only one specific size of each TV is highlighted, most other sizes of each model are also discounted. Just click through to the different sizes on the product pages for more details.
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.

举个例子，比如拍一张有三瓶矿泉水的照片，白天和晚上光线不同，整张图片的色温、亮度都变了，模型可能就不认识了。
I found this article on the subject, and decided to turn that data into a visualization, too.
