Image query system using object probes

This paper presents a novel image-based indexing scheme called object probes. Object probes make use of both physical features and a manually formulated decision tree to classify objects in the scene. A conceptual graph is used to represent the association of the labels found in each labeled image. We develop a query formalism that translates the query elements into a graph structure. The query process can be seen as matching the query graph with those sub-graphs found in the database of images
