Some Novel Methods of Ordered Dither

Sa？etak 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
