    • Image classification using subgraph histogram representation 

      Özdemir, Bahadır; Aksoy, Selim (IEEE, 2010)
      We describe an image representation that combines the representational power of graphs with the efficiency of the bag-of-words model. For each image in a data set, first, a graph is constructed from local patches of interest ...
    • Performance evaluation of building detection and digital surface model extraction algorithms: Outcomes of the PRRS 2008 algorithm performance contest 

      Aksoy, Selim; Özdemir, Bahadır; Eckert, S.; Kayitakire, F.; Pesarasi, M.; Aytekin, O.; Borel, C. C.; Cech, J.; Christophe, E.; Düzgün, S.; Erener, A.; Ertugay, K.; Hussain, E.; Inglada, J.; Lefévrë, S.; Ok, Ö.; San, D. K.; Šára, R.; Shan, J.; Soman, J.; Ulusoy, I.; Witz, R. (IEEE, 2008-12)
      This paper presents the initial results of the Algorithm Performance Contest that was organized as part of the 5th IAPRWorkshop on Pattern Recognition in Remote Sensing (PRRS 2008). The focus of the 2008 contest was automatic ...
    • Structural scene analysis of remotely sensed images using graph mining 

      Özdemir, Bahadır (Bilkent University, 2010)
      The need for intelligent systems capable of automatic content extraction and classi cation in remote sensing image datasets, has been constantly increasing due to the advances in the satellite technology and the availability ...
    • Turkish keyphrase extraction using multi-criterion ranking 

      Özdemir, Bahadır; Çiçekli, İlyas (IEEE, 2009-09)
      Keyphrases have been extensively used for indexing and searching in databases and information retrieval systems. In addition, they provide useful information about semantic content of a document. In this paper, we propose ...
