Proceedings of the 20th annual conference on Computer graphics and …, 1993•dl.acm.orgDot diffusion has been proposed as a way of combining the strengths of ordered dithering
and error diffusion to create a parallelizable halftoning technique. However, dot diffusion
pays a price in image quality in order to achieve parallelizability. Space-filling curves have
been used to improve error diffusion. We show that by combining dot diffusion with a space-
filling curve traversal technique, a parallelizable halftoning technique results that does not

Abstract
Dot diffusion has been proposed as a way of combining the strengths of ordered dithering and error diffusion to create a parallelizable halftoning technique. However, dot diffusion pays a price in image quality in order to achieve parallelizability. Space-filling curves have been used to improve error diffusion. We show that by combining dot diffusion with a space-filling curve traversal technique, a parallelizable halftoning technique results that does not pay a cost in image quality. This new technique we call space diffusion.
