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 :
More plans are afoot to show the objects. Artefacts from the Wendover Saxon cemetery, where 122 graves were unearthed, will soon go on display for the first time at a Discover Bucks Museum exhibition.
