3-D analysis of projective textures using structural approaches

摘要

This paper presents a new algorithm that obtains the surface orientation of the texture image using structural approaches. The proposed method has shown that structural information can be effectively used in three-dimensional (3-D) analysis of textures as well as description and segmentation. By examining 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 a vanishing point, and rearrange the textured surface with the lines converging to the vanishing point and the 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.
