    • Detection of colon glands using subgraph modeling 

      Özgül, E.B.; Sökmensüer, C.; Gündüz-Demir Ç. (2011)
      The colon adenocarcinoma causes changes in glandular structures of colon tissues. Pathologists assess these changes to diagnose and grade the colon adenocarcinoma. However, this assessment may consist of a considerable ...
    • Finding compound structures in images using image segmentation and graph-based knowledge discovery 

      Zamalieva, D.; Aksoy, S.; Tilton J.C. (2009)
      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 G.; Sokmensuer, C.; Gunduz-Demir, C. (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, B.; Aksoy, S. (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 ...
