Learning graph fusion for query and database specific image retrieval

In this paper, we propose a graph-based image retrieval algorithm via query and database specific feature fusion. While existing feature fusion approaches exist for image retrieval, they typically do not consider the image database of interest (i.e., to be retrieved) for observing the associated feature contributions. In the offline learning stage, our proposed method first identifies representative features for describing images to be retrieved. Given a query input, we further exploit and integrate its visual information and utilize graph-based fusion for performing query-database specific retrieval. In our experiments, we show that our proposed method achieves promising performance on the benchmark database of UKbench, and performs favorably against recent fusion-based image retrieval approaches.
