Maintaining Spatial Relations in an Incremental Diagrammatic Reasoner
Because diagrams are often created incrementally, a qualitative diagrammatic reasoning system must dynamically manage a potentially large set of spatial interpretations. This pape...

Spatial Weighting for Bag-of-Features
This paper presents an extension to category classification with bag-of-features, which represents an image as an orderless distribution of features. We propose a method to explo...

Markov Random Fields and Spatial Information to Improve Automatic Image Annotation
Content-based image retrieval (CBIR) is currently limited because of the lack of representational power of the low-level image features, which fail to properly represent the actual...

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...
