We give an algorithm for the estimation of the orientation of a planar surface with a homogeneous texture, viewed under perspective projection. We follow the two step procedure which is usually employed for this type of problem: First, a set of local distortion matrices is estimated – here we use wavelets –, then we determine the surface orientation which best fits the local distortions. In both parts the techniques we use are original.
