    • Automatic detection of compound structures by joint selection of region groups from a hierarchical segmentation 

      Akçay, H. G.; Aksoy, S. (Institute of Electrical and Electronics Engineers, 2016)
      A challenging problem in remote sensing image analysis is the detection of heterogeneous compound structures such as different types of residential, industrial, and agricultural areas that are composed of spatial arrangements ...
    • Automatic detection of compound structures by joint selection of region groups from multiple hierarchical segmentations 

      Akçay, Hüseyin Gökhan (Bilkent University, 2016-09)
      A challenging problem in remote sensing image interpretation is the detection of heterogeneous compound structures such as different types of residential, industrial, and agricultural areas that are comprised of spatial ...
    • Bağlamsal çıkarımla nesne sezimi 

      Kalaycılar, Fırat; Aksoy, Selim (IEEE, 2009-04)
      Bu bildiride, sezim başarımını arttırmada tek tek sezilmiş nesneler arasındaki bağlamsal ilişkilerden yararlanan bir nesne sezim sistemi tanıtılmaktadır. Bu çalışmadaki ilk katkı, iki boyutlu görüntü uzayında yapılan ...
    • Building detection using directional spatial constraints 

      Akçay, H. Gökhan; Aksoy, Selim (IEEE, 2010)
      We propose an algorithm for automatic detection of buildings with complex shapes and roof structures in very high spatial resolution remotely sensed images. First, an initial oversegmentation is obtained. Then, candidate ...
    • Detection of compound structures by region group selection from hierarchical segmentations 

      Akçay, H. G.; Aksoy, S. (Institute of Electrical and Electronics Engineers Inc., 2016)
      Detection of compound structures that are comprised of different arrangements of simpler primitive objects has been a challenging problem as commonly used bag-of-words models are limited in capturing spatial information. ...
    • A framework for applying the principles of depth perception to information visualization 

      Zeynep, C. Y.; Bulbul, A.; Capin, T. (Association for Computing Machinery, 2013)
      During the visualization of 3D content, using the depth cues selectively to support the design goals and enabling a user to perceive the spatial relationships between the objects are important concerns. In this novel ...
    • Image information mining using spatial relationship constraints 

      Karakuş, Fatih (Bilkent University, 2012)
      There is a huge amount of data which is collected from the Earth observation satellites and they are continuously sending data to Earth receiving stations day by day. Therefore, mining of those data becomes more important ...
    • Image mining using directional spatial constraints 

      Aksoy, S.; Cinbiş, R. G. (Institute of Electrical and Electronics Engineers, 2010-01)
      Spatial information plays a fundamental role in building high-level content models for supporting analysts' interpretations and automating geospatial intelligence. We describe a framework for modeling directional spatial ...
    • Konuma bağlı uzamsal ilişkilerin biçimbilimsel modellenmesi

      Uzamsal bilgi, görüntü analizi modellerinde çok önemli bir yer tutmaktadır. Bu bildiride, ikili ve üçlü uzamsal ilişkileri bulmak için, matemaktiksel biçimbilim kullanarak, özelleştirilebilir, gerçekçi ve hızlı yöntemler ...
    • Mining of remote sensing image archives using spatial relationship histograms 

      Kalaycılar, Fırat; Kale, Aslı; Zamalieva, Daniya; Aksoy, Selim (IEEE, 2008-07)
      We describe a new image representation using spatial relationship histograms that extend our earlier work on modeling image content using attributed relational graphs. These histograms are constructed by classifying the ...
    • An object recognition framework using contextual interactions among objects 

      Kalaycılar, Fırat (Bilkent University, 2009)
      Object recognition is one of the fundamental tasks in computer vision. The main endeavor in object recognition research is to devise techniques that make computers understand what they see as precise as human beings. The ...
    • Relative position-based spatial relationships using mathematical morphology 

      Cinbiş, R. Gökberk; Aksoy, Selim (IEEE, 2007-09-10)
      Spatial information is a crucial aspect of image understanding for modeling context as well as resolving the uncertainties caused by the ambiguities in low-level features. We describe intuitive, flexible and efficient ...
