abstract = {Digital halftoning remains an active area of research with a
plethora of new and enhanced methods. While several fine overviews
exist, this purpose of this paper is to review retrospectively the
basic classes of techniques. Halftoning algorithms are presented
by the nature of the appearance of resulting patterns, including
white noise, recursive tessellation, the classical screen, and
blue noise. The metric of radially averaged power spectra is
reviewed, and special attention is paid to frequency domain
characteristics. The paper concludes with a look at the components
that comprise a complete image rendering system. In particular
when the number of output levels is not restricted to be a power
of 2. A very efficient means of multilevel dithering is presented
based on scaling order- dither arrays. The case of real-time video
rendering is considered where the YUV-to-RGB conversion is
incorporated in the dithering system. Example illustrations are
included for each of the techniques described.},
