摘要
本文简要回顾与总结了连续调图像复制技术的主要类型以及它们的优缺点,包括全局固定阈值算法、自适应局部阈值法、正字阶调等级表示算法、电子加网技术、伪随机阈值法(有序抖动)和误差扩散算法。
A brief review and evaluation to reproduction technologies of continuous tone images was given in this paper ineluding globally fixed level thresholding, locally adaptive thresholding, orthographic tone scale creation, electronic screening, pseudorandom thresholding (ordered dither) and error difussion algorithm.
