  title = {{A} {M}arkovian {F}ramework for {D}igital {H}alftoning},
  abstract = {A mathematical framework for digital halfloning is proposed. Two
              models for digital halftoning are provided, one based on
              maximum-entropy Gibbs measures and one based on reversible Markov
              chains. The models are seen to be equivalent. This equivalence
              induces an equivalence between two associated halftoning
              algorithms, one based on neural networks and one based on
              simulated annealing. These algorithms are seen to provide halftone
              images that are preferable to those obtained by standard
              techniques.},
