| Title: | An error diffusion technique with reduced directional hysteresis | Authors: | Chan, YH Kwong, HT Lo, KT Li, CK |
Issue Date: | 1999 | Source: | ISCAS'99 : proceedings of the 1999 IEEE International Symposium on Circuits and Systems : May 30-June 2, 1999, Orlando, Florida, p. IV263-IV266 | Abstract: | In this paper, a digital halftoning method is proposed to diffuse error with a more symmetric error distribution by making use of the concept of delayed decision. It can improve the diffusion performance by effectively reducing the directional hysteresis. A corresponding dot-overlap compensation scheme is also proposed to eliminate the bias in the gray scale of the printed images. | Keywords: | Decision theory Error correction Image enhancement Image quality |
