Model-driven Selection using Texture.

In this paper we explore the use of texture or pattern information on a 3D object as a cue to isolate regions in an image that are likely to come from the object. We develop a representation of texture based on the linear prediction (LP) spectrum that allows the recognition of the model texture under changes in orientation and occlusions. The candidate matching image regions are obtained without detailed segmentation by a technique called overlapping window analysis. This analysis, under some conditions, guarantees the existence of a window spanning only the model texture regardless of its position and orientation which is sufficient for the recognition of the model texture using the LP spectrum representation. Finally, we evaluate the utility of texture-based selection in combination with other cues such as color in the context of reducing the search involved in recognition.
