3-D analysis of textures using structural information

This paper presents a new algorithm that obtains the surface orientation of the texture image using structural approaches. The proposed method showed that structural approaches can be effectively used in 3-D analysis of textures as well as description and segmentation. By examining the Fourier power spectrum of the texture image, we determine the tilt of the textured surface. Then, 1-D projection information of the texture in the obtained tilt direction is used to compute the slant. Using the obtained information, we can compute the vanishing point, and rearrange the textured surface with lines converging to the vanishing point and lines perpendicular to the tilt. In the experimental results, we have ascertained the proposed method can make a precise 3-D analysis of structural textures
