Sažetak

Various authors have contributed their original works in the field of digital halftoning
during past two to three decades. Still this field has not lost its glory. The goal of the
study was to investigate novel methods in digital halftoning specially, in ordered dithering.

This paper is concerned with two novel methods of ordered dither. In the first method
dithering is done first by pre-embedding a pattern image generated from a matrix pattern
with the original image. In the second method dithering is done by thresholding
the original image with respect to a threshold matrix pattern constructed using a character
writing pattern.
The two methods may be applied in digital halftone reproduction and as special effect
imaging.
