Mental representations of spatial relations
Cognitive Psychology, 1986Abstract Three classes of theories of the mental representation of spatial relations were tested. Nonhierarchical theories propose that spatial relations among objects in an environment are mentally represented in networks or in imagelike, analog formats.

On computing temporal/spatial relations
Information Sciences, 1998Abstract In this paper, we analyze the domains of interval temporal relations. A set of algorithms is proposed to derive reasonable relations between intervals. Possible conflicts in the user specification are firstly detected and eliminated. The algorithm is extended for objects in an arbitrary n -dimensional space.

A Representation Theorem for Spatial Relations
2015Spatial relations have been investigated in various inter-related areas such as qualitative spatial reasoning (for agents moving in an environment), geographic information science, general topology, and others. Most of the results are specific constructions of spatial relations that fulfill some required properties.

Topological Relations in Spatial Databases
2002Various models for the representation of topological relations have been developed. The aim of this chapter is to propose a comprehensive view of state-of-the-art models for topological relations in spatial databases. A prominent role is assumed by the CBM (calculus-based method), which offers a small set of topological relations with high ...

Vague Relations in Spatial Databases
2010While qualitative relations (e.g. RCC8 relations) can readily be derived from spatial databases, a more difficult matter is the representation of vague spatial relations such as 'near-to', 'next-to', 'between', etc. After surveying earlier approaches, this paper proposes a method that is tractable, learnable and directly suitable for use in natural ...

Fuzzy Models of Spatial Relations, Application to Spatial Reasoning
2013Spatial relations are an important component of image content, that proved to be useful for recognition of individual objects and for image understanding. Indeed, spatial relations provide structural information about the scene, which is often more stable that individual object characteristics, can help disambiguating objects of similar appearance, and
