Estimation of Surface Normal of a Curved Surface Using Texture

Shape-from-Texture is the problem of estimating an object’s shape by examining the apparent distortions in the surface texture of the object due to image capture. A new method is described for estimating the tilt angle of local surface patches, based on an analysis of the spectral inertia. The effectiveness of the method is demonstrated on synthetic images generated using the Brodatz textures, as well as a real image.
