    • Altçizge modellemesi kullanarak kolon bez tespiti 

      Özgül, Etkin Barış; Sökmensüer, C.; Gündüz-Demir, Çiğdem (IEEE, 2011-04)
      Kolon adenokarsinomu, kolon bez yapılarında değişimlere yol açar. Patologlar bezlerdeki bu değişimleri değerlendirerek kolon adenokarsinom tanı ve derecelendirmesi yaparlar. Ancak değişimlerin değerlendirme süreci kaydadeğer ...

    • Finding compound structures in images using image segmentation and graph-based knowledge discovery 

      Zamalieva, Daniya; Aksoy, Selim; Tilton J. C. (IEEE, 2009-07)
      We present an unsupervised method for discovering compound image structures that are comprised of simpler primitive objects. An initial segmentation step produces image regions with homogeneous spectral content. Then, the ...

    • Graph walks for classification of histopathological images 

      Olgun, Gülden; Sokmensuer, C.; Gündüz-Demir, Çiğdem (IEEE, 2013)
      This paper reports a new structural approach for automated classification of histopathological tissue images. It has two main contributions: First, unlike previous structural approaches that use a single graph for representing ...

    • 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 ...
