Joint linear-circular stochastic models for texture classification

Abstract: In this paper, we investigate both linear and circular stochastic models in the context of texture discrimination. These models aim at representing the magnitudes and orientations obtained by a complex wavelet decomposition, such as the steerable pyramid.The novelty consists in considering specific parametric models for circular data such as von Mises and ψ-distributions to describe the distributions of orientations. Particular attention is paid to the choice of a metric and to its adequation to the models. In… Show more

“…Some recent works propose to use circular statistics, i.e. statistics of circular data [15] or joint linear-circular stochastic model [16] to characterize each subband coefficients. All these representation leads to a simple and attractive approach, defined by a limited set of parameters, but they do not provide a complete statistical description of the texture images.…”
