               ``Shape From Texture": Estimating the Orientation
                  of Planar Surfaces -- Algorithms and Bounds

The perspective projection has a dominant and fundamental role in any imaging process, whether by the human visual system, or by some type of a camera. Hence, perspective is one of the prominent clues in image interpretation and understanding. This makes perspective estimation a key problem in many image modeling and analysis applications.

In this presentation we address a special case of this general problem:  We consider the problem of estimating the orientation in space of a planar textured surface, from a single, noisy, observed image of it.
