AbstractIn this paper we investigate the problem of varying the of dots in digital halftoning processes. We show that the dot size is the main factor determining the tradeoff between tonal and spatial resolution in the context of dithering algorithms. In particular, we extend the dither with space filling curves method, introduced in (Velho & Gomes, 1991), to change the size of pixel clusters according to local characteristics of the image. This makes possible to achieve optimal rendition of gray shades while preserving image details.
