  This paper presents a new framework for oriented texture modeling. We
introduce a new class of Gaussian fields, called Locally Anisotropic Fractional
Brownian Fields, with prescribed local orientation at any point. These fields
are a local version of a specific class of anisotropic self-similar Gaussian
fields with stationary increments. The simulation of such textures is obtained
using a new algorithm mixing the tangent field formulation and a turning band
method, this latter method having proved its efficiency for generating
stationary anisotropic textures. Numerical experiments show the ability of the
method for synthesis of textures with prescribed local orientation.
