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 :
He decided to create a new kind of visual communications company, called SpeedPro. The vision was simple but ambitious: Don’t just print, be the last mile of visual marketing. Make a brand impossible to ignore — on walls, windows, floors, vehicles, and every surface a customer might see. The tagline is: “Great. Big. Graphics.”
