Row-oriented multiscale error diffusion technique for digital halftoning

Abstract

A digital halftoning method is proposed to diffuse error with a more symmetric error distribution by making usc of the concept of multiscale error diffusion. The method can improve the diffusion performance by effectively reducing directional hysteresis. The diffusion is row-oriented rather than frame-oriented and hence can reduce the latency and computational effort as compared with conventional multiscale error diffusion schemes. This makes it possible for real-time applications.
