Properties of Jointly-Blue Noise Masks and Application on Color Halftoning

It has been shown that dithering with blue noise is useful for producing visually pleasing halftone images. For color halftoning, the goal of blue noise mask design is to generate a set of blue noise masks which produce high quality blue noise patterns when they are used individually or jointly. In this paper, an approach is proposed which is based on digital filter techniques and can be used to generate a set of jointly-blue noise masks. Each mask from the set of the masks will be applied to one color plane. The jointly blue noise masks possess the properties such that each individual mask is blue noise, also the combinations of the masks produce color images with blue noise characteristics, e.g., the dots of different color are mutually exclusive and maximally dispersed on the combined plane at highlight levels. Several other schemes which have been developed are also reviewed in this paper. Examples of output color images created by the approach and other schemes are given.
