Structure of aura and co-occurrence matrices for the Gibbs texture model

  title={Structure of aura and co-occurrence matrices for the Gibbs texture model},
  author={Rosalind W. Picard and Ibrahim M. Elfadel},
  journal={Journal of Mathematical Imaging and Vision},
The aura matrix of an image indicates how much of each gray level is present in the neighborhood of each other gray level and generalizes the popular texture-analysis tool, the co-occurrence matrix. In this paper we show that interesting structure appears in both the aura and co-occurrence matrices for textures that are synthesized from Gibbs random-field models. We derive this structure by characterizing configurations of the distribution that are most likely to be synthesized when the Gibbs… CONTINUE READING
