Abstract : This paper explores two different methods to capture the local anisotropy of locally parallel textures. The corresponding models allow for both an analysis and a synthesis of oriented patterns. The first method models such textures as local oscillations that can be analyzed by a windowed Fourier transform. The resulting model can be sampled by alternating projections that enforce the consistency of the local phase with the estimated spectrum of the input texture. The second method models the texture over the domain of local structure tensors. These tensors encode the local energy, anisotropy and orientation of the texture. The synthesis is performed by matching the multiscale histograms of the tensor fields.
