  This paper presents two new models of oriented texture, based on 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 with the Cholesky method or the 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.
