概要 |
We propose a method for extending grayscale error diffusion to color on the basis of Neugebauer model for color representation. The grayscale Neugebauer model corresponds to grayscale error diffusion.... Extending the grayscale Neugebauer model to its color version, we obtain a color error diffusion method based on the color Neugebauer model in a natural way. Experimental results show that the resultant color halftone images preserve the color contents in original continuous-tone images better than the results of conventional color error diffusion.続きを見る
