In recent years there has been increasing interest in constructing cognitive vision systems

We present a highly expressive logical language for describing qualitative configurations of
spatial regions, based on Tarski's Geometry of Solids, in which the parthood relation and the …

Abstract Region Based Geometry (RBG) is an axiomatic theory of qualitative configurations
of spatial regions. It is based on Tarski's Geometry of Solids, in which the parthood relation …

This paper presents a theory that supports commonsense, qualitative reasoning about the
flow of liquid around slowly moving solid objects; specifically, inferring that liquid can be …

I present a logical language for describing spatial, temporal and material properties of the
physical world. The formalism is ontologically well-founded in the sense that it is interpreted …

We present a commonsense, qualitative model for the semantic grounding of embodied
visuo-spatial and locomotive interactions. The key contribution is an integrative methodology …
