Dispersed dot ordered dithering
WebJan 15, 2006 · This paper presents a generalization of dispersed-dot dithering. While existing methods such as Bayer's assume that color dots are arranged in a square matrix, this method works with arbitrarily-placed color points. To create a good dither pattern for arbitrarily-placed points, they must be ordered so that consecutive pairs are maximally … WebSep 8, 1993 · This new stochastic screen algorithm is loosely based on Kang's dispersed-dot ordered dither halftone array construction technique used as part of his microcluster …

WebNov 16, 1994 · This paper examines the possibilities of improving halftoning techniques using dispersed dots. This corresponds to finding micro-dot distributions that approximate the intensity levels that have to be rendered. A widely used halftoning method is ordered dithering, which uses a threshold matrix to decide if a micro-dot should be set in the … WebOrdered Dither • For a constant gray level patch, turn the pixel “on”in a specified order. ...
