Shape from Texture

Categories: Vision


Author(s): T.P. Pridmore, S.R. Pollard, S.T. Stenton

Shape from texture is the process by which the three-dimensional structure of a surface is determined from the spatial distribution of surface markings. Projection into the image plane distorts the geometry of surface textures in a manner dependent upon the shape of the underlying surface: as a surface recedes from the viewer its markings appear smaller due to perspective effects, and as a surface is inclined away from the frontal plane its markings appear compressed in the direction of the inclination. By isolating these projective distortions it is possible to recover the shape of a textured surface.
