… On the opposite end of the coarseness spectrum, green noise benefits from its stochastic
arrangement of clusters, and because the eye is … halftones, green noise has better visual
fidelity than periodic clustered-dot halftones with the same average cluster size. Green noise …

… of green noise—the midfrequency component of white noise—and its advantages over blue
noise for digital halftoning. Unlike blue-… Introducing the green-noise model to digital halftoning
is the primary focus of this paper. Because of the tunability of AM–FM hybrids to create …

… We introduce a novel technique for generating green-noise halftones—stochastic dither
patterns composed of homogeneously distributed pixel … of halftoning by using green-noise
masks, dither arrays designed to generate halftone screens that closely approximate green noise. …

… Yao and Parker [10] have even introduced the blue-noise mask to color halftoning. This
paper introduces, to color printing, green-noise halftoning. The first technique extends error
diffusion with output-dependent feedback to not only cluster pixels of like color but also to …

… As a last component to greennoise, the first edition of this book addressed green-noise’s
application to color printing where the primary task is to reproduce color as accurately as possible
without introducing visible moiré patterns. While color printers were once very expensive …

… for producing a green-noise mask for use in a method for producing a halftone image
from a gray-scale image, the green-noise mask … the green-noise mask a value defined by
a gray level at which a corresponding pixel in the sequence of binary dot profiles is turned “on.” …

… Its success in providing a blue-noise halftone motivates us to explore whether the MED framework
… green noise halftoning which aims at providing halftones of green noise characteristics.
In this paper, a MED algorithm is proposed to produce halftones of desirable green noise …

… halftoning and 2) green noise halftoning. In edge enhancement … in green noise halftoning.
Section VI concludes the paper. In the Appendix, we prove that in the case of edge enhancement
halftoning (aka, modified error diffusion halftoning) and green noise digital halftoning, our …

… To further achieve the objects, the present invention comprises an apparatus and method of
color printing using green-noise halftoning, the method comprising the step of: incorporating
a desired correlation between colors to construct a vector green-noise mask, wherein the …

… Green-noise halftoning is a stochastic halftoning technique where the minority pixels of a
binary dither pattern form homogeneously … Halftoning techniques which create stochastic
patternings of clustered dots fall into the general category of greennoise halftoning. Their …
