Hybrid Halftoning : A novel Algorithm for Using Multiple Halftoning Technologies

• The rendering quality in halftoning is a critical issue. The quality aspects are more important in some images than in others. The quality of skin tone rendering of halftoned images generated by frequency modulated (FM) halftoning techniques differs from those generated by conventional halftoning techniques. Some judge the conventional halftoning techniques as superior in smoothly varying tones whereas frequency modulated halftoning techniques excel in heavily textured images. This paper describes an algorithm that can incorporate both technologies simultaneously. The technique is an iterative optimization of the binary halftone image with respect to the differences between the original and the halftoned images. The performance of the algorithm can be controlled by the nature of the original state of the iteration. The algorithm can in effect accommodate any type of halftone that can be described by a threshold matrix.
