Abstract
Ordered dither (C. N. Judice, J. F. Jarvis, and W. H. Ninke, inProceedings of the S.I.D. 15, 4(Fourth Quarter),1974,pp. 161–169.) is an efficient and widely used halftoning technique. One disadvantage with this method is that it produces blurred images. Recently, a space-filling curve ordered dithering approach (Y. Zhang, submitted for publication.) has been proposed that improves the ordered dither in image quality by generating clustered dot patterns along a space-filling curve over the image. In this method the cluster size is fixed in the process of halftoning. This paper presents a new ordered dithering method, called adaptive ordered dither, that does halftoning by using a space-filling curve to perform an adaptive variation of the cluster size. Experimental results demonstrate that the new method can significantly improve the space-filling curve ordered dither in revealing image details.
(C. N. Judice, J. F. Jarvis，和W. H. Ninke，刊于《美国科学院院刊》第15卷第4期，1974年，第4页)。(161-169 .)是一种高效且应用广泛的半调色技术。这种方法的一个缺点是它会产生模糊的图像。最近，提出了一种空间填充曲线有序抖动方法(Y. Zhang，已提交发表)，该方法通过在图像上沿空间填充曲线产生聚类点模式来改善图像质量的有序抖动。在这种方法中，在半色调过程中簇大小是固定的。本文提出了一种新的有序抖动方法，即自适应有序抖动，该方法利用空间填充曲线来实现簇大小的自适应变化，从而实现半调。实验结果表明，该方法能显著改善图像细节显示中的填充曲线有序抖动。
