Abstract


The emerging discipline of cognitive vision requires a proper representation of visual information including
spatial and temporal relationships, scenes, events, semantics and context. This review article summarizes
existing representational schemes in computer vision which might be useful for cognitive vision,
and discusses promising future research directions. The various approaches are categorized according to
appearance-based, spatio-temporal, and graph-based representations for cognitive vision. While the representation
of objects has been covered extensively in computer vision research, both from a reconstruction
as well as from a recognition point of view, cognitive vision will also require new ideas how to represent
scenes. We introduce new concepts for scene representations and discuss how these might be efficiently
implemented in future cognitive vision systems.
