                         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.",
