Abstract
In digital halftoning, moiré refers to the periodic interference pattern created by superimposing the cyan, magenta, yellow, and black halftone patterns of periodic amplitude modulated screens. This paper introduces the concept of stochastic moiré - the aperiodic interference pattern created by superimposing the aperiodic halftone patterns of frequency modulated screens. Given two overlapping stochastic halftone patterns, this paper details how to extract a continuous-space surface that completely characterizes the spatial fluctuations in color/texture of stochastic moiré that exist in the halftone. To quantitatively measure the visibility of stochastic moiré, this paper introduces a statistic for characterizing the fluctuations in color/texture that result from stochastic moiré and shows how this metric can be used to identify the better of two arrangements of dots at minimizing the visual distortion stochastic moiré creates.
