    • De-Emphasis of Distracting Image Regions Using Texture Power Maps 

      Su, Sara L.; Durand, Frédo; Agrawala, Maneesh (2006-01)
      We present a post-processing technique that selectively reduces the salience of distracting regions in an image. Computational models of attention predict that texture variation influences bottom-up attention mechanisms. ...

    • BATON: A Balanced Tree Structure for Peer-to-Peer Networks 

      Jagadish, H.V.; Ooi, Beng Chin; Rinard, Martin C.; Vu, Quang Hieu (2006-01)
      We propose a balanced tree structure overlay on a peer-to-peer network capable of supporting both exact queries and range queries efficiently. In spite of the tree structure causing distinctions to be made between nodes ...

    • Addressing the Challenges of Aggregational and Temporal Ontological Heterogeneity 

      Zhu, Hongwei; Madnick, Stuart E. (2006-01)
      In this paper, we first identify semantic heterogeneities that, when not resolved, often cause serious data quality problems. We discuss the especially challenging problems of temporal and aggregational ontological ...
