Abstract : In this poster, we present an overview of the structure tensor model. We first recall the general ideas developped in this framework: model of V1 seen as a set of hypercolumns which encode texture via the structure tensor. We present and analyse analog of Wilson-Cowan equations written in the feature space of 2x2 symmetric definite positive matrices. We show that this model englobes the well-known ring model of orientation. We present some results about two classes of specific stationary solutions of the system.
