Paper Abstract

A modified error diffusion algorithm that results in a homogenous pulse distribution in the highlight and shadow areas of the binarized images is described. The distinction to standard error diffusion algorithms is a dynamic threshold imprint function that depends on the local input values and binary output pixel. The imprint function is generated by diffusing a one-dimensional function in the orthogonal direction, thereby allowing a fast implementation of a two-dimensional threshold imprint.
