Error diffusion for color images with semi-vector quantization

摘要: A method for color error diffusion using semi-vector quantization is proposed that simplifies calculations. When three separations are used, the two with most visually perceptive output compared one another to determine their colors, while third, least separation, treated separately. correction term may be applied third separation based on of first insure uniformity ink coverage. This yields results close vector and also minimizes fluctuation in colors. Of course, this used more than separations. For example, when four processed differently other
