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 multiscale error diffusion. It can improve the diffusion performance by effectively reducing directional hysteresis. The diffusion is row-oriented rather than frameoriented and hence can reduce a lot of computation effort as compared with conventional multiscale error diffusion schemes. This makes it possible for real-time applications.doi:10.1109/icip.2000.899626 dblp:conf/icip/ChanC00 fatcat:ybzi6h3afvce7jvvxbryivhg3m
