Abstract
In this paper a new method of minimizing the unwanted texture in two-level rendition of continuous-tone pictures is described. A rule based on making the Fourier spectra of all level patterns similar is proposed and the subjective quality evaluation turns out to support this rule. We have the freedom of selecting a discrete specific wave length as a parameter and it is made clear that this parameter is closely related to several aspects of picture quality. We examine both the micro font method and the ordered dither method and the relation is discussed for both cases.
