Target patterns controlled error management |
摘要 |
A system and method to print grey scale or color images using fewer colors of ink than in the original image. This method distributes the error made at each point (due to the embodied approximation) to the neighbors of that point while obtaining some chosen predetermined patterns for several colors or grey levels. Getting these predetermined patterns and essentially predetermined patterns for all colors in turn reduces the anisotropic algorithmic artifacts, suppresses edge over-enhancement and allows for good performances on patches of uniform and almost uniform colors or grey levels.
