當被問及代表美國參賽的意義時，赫斯坦言：「這有點困難。僅因我披著國旗，並不代表我認同美國正在發生的所有事情。」
Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :，详情可参考爱思助手下载最新版本
