概要

• 論文の詳細を見る

• The interpolation of color pixel values prior to digital halftoning is discussed and a new color interpolation sheme is presented by a directional copy of color values in the gradient field of luma. Error diffusion quantization is combined with clustered-dot ordered dithering to prevent from contouring. Experimental results demonstrate that sharp and false color-free interpolation is obtained to produce color bilevel AM halftones with weak rosettes and no contouring artifacts.
