Shape from non-homogeneous, non-stationary, anisotropic, perspective texture

Abstract

We present a method for Shape-from-Texture in one of its most general forms. Previous Shape-from-Texture papers assume that the texture is constrained by one or more of the following properties: homogeneity, isotropy, stationarity, or viewed orthographically. We make none of these assumptions. We do not presume that the frontal texture is known a priori, or from a known set, or even present in the image. Instead, surface smoothness is assumed, and the surface is recovered via a consistency constraint. The key idea is that the frontal texture is estimated, and a correct estimation leads to the most consistent surface. In addition to surface shape, a frontal view of the texture is also recovered. Results are given for synthetic and real examples. Show more
