The cooperative control technology of robot formation can sense all kinds of external
environment in real time. It is a multi-functional control and management system including …

The ability to perform spatial tasks is crucial for everyday life and of great importance to
cognitive agents such as humans, animals, and autonomous robots. Natural embodied and …

An approach for scene understanding based on qualitative descriptors, domain knowledge
and logics is proposed in this paper. Qualitative descriptors, qualitative models of shape …

Computational models of novel concept understanding and creativity are addressed in this
paper from the viewpoint of conceptual blending theory (CBT). In our approach, a novel …

A qualitative model for describing 3D objects (Q3D) using depth and different perspectives is
presented in this paper. The front, right and up perspectives are considered as canonical …

A logical approach to compose qualitative shape descriptors (LogC-QSD) is presented in
this paper. Each object shape is described qualitatively by its edges, angles, convexities …

Partial singleton weak path-consistency, or partial Image 1-consistency for short, is essential
for tackling challenging fundamental reasoning problems associated with qualitative …

Paper folding-and-punching tests are used to measure spatial abilities in humans. This
paper presents a qualitative model for paper folding (QPF) and a computer game (Paper …

The extraction of geometric information from the environment may be of interest to
localisation and mapping algorithms. Existent literature on extracting geometric features …
