Introducing Context and Reasoning in Visual Content Analysis: An Ontology-based Framework

Semantic Multimedia and Ontologies: Theory and Applications, Springer-Verlag, pp.99-122, January 2008.

In this chapter,we propose an ontology-based framework for enhancing segment-level annotations resulting from typical image analysis, through the exploitation of visual context and topological information. The concepts (objects) of interest and their spatial topology are modelled in RDFS ontologies, and through the use of reification, a fuzzy ontological representation is achieved, enabling the seamless integration of contextual knowledge. The formalisation of contextual information enables a first refinement of the input image analysis annotations utilising the semantic associations that characterise the context of appearance.
