Clustered AM/FM Halftoning Algorithm
Abstract:In this paper, we present a hybrid halftoning algorithm called clustered AM/FM halftoning. It is a generalization of the AM/FM halftoning algorithm developed by the authors earlier. With tone-dependent clustering strength control, the algorithm generates dispersed-dot halftone as error diffusion in highlight area and clustered-dot halftone similar to clustered-dot screen in mid-tone and shadow areas. The transition of the halftone texture is smooth. Moreover, the algorithm shows good Moiré resistence. There-fore, it may be especially suitable for such application as electro-photograpic multi-function printer.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
