Abstract
This paper is a description of a framework for reasoning about textured scenes where low level structural information is used as evidence for texture primitives instead of a particular texture. Although low level texture edge features are not robust enough to determine exactly the texture in the scene, they can be used to reason about the scene since they provide evidence about the type of texture present. The structural evidence is combined to determine a measure of belief in the type of texture in the scene. Our overall goal is to use texture as a cue to separate surfaces in a scene. Segmenting textures into homogeneous regions must be based on properties of the texture that are not affected by an oblique projection. Our earlier results using project invariants showed that invariants of low level features cannot reliably discriminate textures. This lead us to an approach to first identify the type of texture element, and then the tesselation of the texture elements. Projective invariants based on the tesselation can then be used to segment the scene. In this paper, the reasoning framework and low level features will be described, along with the results of some experiments using Brodatz textures.
