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 :
I just learned about the Svalboard. I’m interested in it for the ergonomics and the magnetic switches. I’m all about a weird-looking keyboard, but I do feel it would be a downgrade in terms of aesthetics and elegance compared to the Voyager. I’m pondering taking that plunge.，推荐阅读旺商聊官方下载获取更多信息
