Object retrieval in image databases using image composition

Sylvie Philipp-FoliguetM. Lekkat

In order to retrieve images containing a specific object or group of objects, this paper proposes an algorithm of graph matching, adapted to adjacency graphs of regions. The number of regions representing the object can be different from an image to the other, so the algorithm performs inexact matching. It uses a search tree in which only similar nodes are developed. The adjacency and spatial relationship of regions are used to prune the tree and accelerate the retrieval. The algorithm computes a distance between graphs, allowing to rank images. This distance takes into account both the distance between region features and the relative position of regions.
