3-D analysis of projective textures using structural approaches

This paper presents a new algorithm that obtains the surface orientation of the texture image using structural approaches. The proposed method has sho wn that structural information can be effectively used in three-dimensional (3-D) analysis of textures as well as description and segmentation. By exa mining Fourier power spectrum of the texture image, we determine the tilt o f the textured surface. Then, 1-D projection information of the texture in the obtained tilt direction is used to compute the slant. Using the obtaine d information, we can compute a vanishing point, and rearrange the textured surface with the lines converging to the vanishing point and the lines per pendicular to the tilt. In the experimental results, we have ascertained th e proposed method can make a precise 3-D analysis of structural textures. ( C) 1999 Pattern Recognition Society. Published by Elsevier Science Ltd.
