Abstract :
In this paper, an efficient image content representation is proposed, which is appropriate for content-based indexing and retrieval. In particular, the image content is represented by a hierarchical graph, constructed in a tree or pyramid structure framework. The basic concept is to represent the spatial relations of the objects in the image with an image-graph and then, the object details with an object-graph. Further decomposition of the objects regions is permitted in a hierarchical framework
