Pareto-depth for Multiple-query Image Retrieval
Ko-Jen Hsiao, Jeff Calder Alfred O. Hero III
Most content-based image retrieval systems consider either one single query, or multiple queries that include the same object or represent the same semantic information. In this paper we consider the content-based image retrieval problem for multiple query images corresponding to different image semantics. We propose a novel multiple-query information retrieval algorithm that combines the Pareto front method (PFM) with efficient manifold ranking (EMR). We show that our proposed algorithm outperforms state of the art multiple-query retrieval algorithms on real-world image databases. We attribute this performance improvement to concavity properties of the Pareto fronts, and prove a theoretical result that characterizes the asymptotic concavity of the fronts. We also present a graphical user interface (GUI) that allows the user to explore the Pareto fronts and visualize the partially ordered relationships between the queries and the images in the database.
