Shape from Texture
Measurements on image texture interpreted under an approximate perspective image model can be used with an iterative constraint propagation algorithm to determine surface orientation. An extension of the ideas allows their robust application to natural images of textured planes. The techniques are demonstrated on synthetic and natural images.
متن کاملShape from Texture: Homogeneity Revisited
The objective of this paper is to estimate the orientation of a scene plane from an uncalibrated perspective image under the assumption that the scene is coated with a homogeneous (but unknown) texture. We make the following novel contributions: first, we show that the problem is equivalent to estimating the vanishing line of the plane; second, we show that estimating the two degrees of freedom...
متن کاملShape from Texture through Deformations
This paper is a contribution to the recovery of shape from texture under perspective projection. We regard shape from texture as a statistical estimation problem, the texture being the realization of a stochastic process. There are two minimal conditions in order for the problem to be solvable: the first is a stationarity condition on the texture with respect to the surface; the second is the r...
متن کاملShape from Texture and Integrability
We describe a shape from texture method that constructs a maximum a posteriori estimate of surface coefficients using both the deformation of individual texture elements — as in local methods — and the overall distribution of elements — as in global methods. The method described applies to a much larger family of textures than any previous method, local or global. We demonstrate an analogy with...
متن کاملShape From Texture: Integrating Texture-Element Extraction and Surface Estimation
A perspective view of a slanted textured surface shows systematic changes in the density, area, and aspect-ratio of texture elements. These apparent changes in texture element properties can be analyzed to recover information about the physical layout of the scene. However, in practice it is difficult to identify texture elements, especially in images where the texture elements are partially oc...
