Uncertain views

The possibility that what we do not know about the world can be used to guide the way in which they explore it is raised. The authors previously hypothesized that the spatial structure of uncertainty can be used to guide the acquisition of additional data in a way that significantly improves knowledge of a scene. An exploration strategy based on the hypothesis is constructed, and experimental results which verified that it works are presented. Conditions which cause it to break down are studied. The results indicate that there are inherent degeneracies in certain data configurations, but that the authors' strategy can navigate these areas successfully.>
