Combinaison ontologie et satisfaction de contraintes pour la reconnaissance d'objets dans des images satellitaires haute résolution
Abstract
With increasing urbanization and the complexity of modern infrastructures, recognizing
complex objects in high and very high spatial resolution satellite images has become a major
challenge, especially in urban environments. Deep learning-based methods, while powerful,
often require large annotated datasets and struggle to model the complex spatial and contextual
relationships between urban objects. This paper proposes a dual-level hybrid approach that
integrates evolving ontologies with Constraint Satisfaction Problems (CSP) to model complex
objects, while improving their resolution efficiency through a method combining FAC-3, backjumping
and particle swarm optimization (PSO). The main objective is to improve complex
object recognition by simultaneously modeling spatial and semantic relationships while optimizing
the exploration of possible solutions. CSP captures spatial constraints, FAC-3 reduces
the search space, and PSO avoids local minima, enhancing overall search efficiency. The
formalization of the ontology, CSPs and their translation into SWRL rules, as well as their
use, are detailed. Finally, an illustrative application of complex urban object recognition is
presented.
