Abstract
The author present his halftoning technique as an analytical 2-D extension of Σ-Δ modulation, which is proven to feature optimal characteristics for the halftoning problem. A particular effort is devoted to transforming the sequential expression of Σ-Δ modulation into a parallel and dimension-independent expression. This allows a precise understanding of the halftoning action in the frequential domain, while explaining the good experimental performance of the method
