Spatial-Depth Super Resolution for Range Images
We present a new post-processing step to enhance the resolution of range images. Using one or two registered and potentially high-resolution color images as reference, we iterativ...

Applying Spatial Reasoning to Topographical Data with a Grounded Geographical Ontology
Abstract. Grounding an ontology upon geographical data has been proposed as a method of handling the vagueness in the domain more effectively. In order to do this, we require meth...

Spatial logics with connectedness predicates
Abstract. We consider quantifier-free spatial logics, designed for qualitative spatial representation and reasoning in AI, and extend them with the means to represent topological c...

Unifying encoding of spatial information in mutual information for nonrigid registration
As encoding spatial information into mutual information (MI) can improve the nonrigid registration against bias fields where the conventional MI is challenged, we propose to unify ...

Grid-Aware Evaluation of Regular Path Queries on Spatial Networks
Regular path queries (RPQs), expressed as regular expressions over the alphabet of database edge-labels, are commonly used for guided navigation of graph databases. While convenie...
