Multilevel halftoning using multiscale error diffusion
Author(s): Yik-Hing Fung; Yuk-Hee Chan

Paper Abstract

Advances in printing technology has made multilevel halftoning become important, as printers can now print inks of different intensities. This work presents a multilevel halftoning algorithm based on multiscale error diffusion. This algorithm takes care of constrained pixels before handling the unconstrained pixels, and diffuses errors with a noncausal filter such that halftones of better image quality can be achieved.
