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 :

Runaway immigration can have its economic downsides. The Deloitte report noted that a large and sudden influx of immigrants can strain local and state-level budgets, while some research has found that immigration waves can lead to a short-term rise in housing prices. A 2025 Penn-Wharton analysis of the economic effects of Trump’s sweeping deportations also reported some potential wage benefits. It found that a 10-year campaign targeting unauthorized immigrants could lead to a 5% wage gain for low-skilled authorized immigrants and native-born Americans owing to less competition.。WPS官方版本下载是该领域的重要参考
