发明名称 Ink reduction error diffusion
摘要 A method and apparatus for performing ink reduction error diffusion are described. In one embodiment, the method comprises performing vector error diffusion and mapping anchors to printing colors, where performing vector error diffusion includes quantizing each input pixel value to a closest anchor in an anchor set, calculating errors based on differences between the input pixel values and the anchors, and performing error filtering based on calculated errors.
