    • Detection of compound structures using multiple hierarchical segmentations 

      Akçay, Hüseyin Gökhan; Aksoy, Selim (IEEE, 2014)
      In this paper, we present a method for automatic compound structure detection in high-resolution images. Given a query compound structure, our aim is to detect coherent regions with similar spatial arrangement and ...
    • SAR image reconstruction by expectation maximization based matching pursuit 

      Ugur, S.; Arıkan, Orhan; Gürbüz, A. C. (Academic Press, 2015)
      Synthetic Aperture Radar (SAR) provides high resolution images of terrain and target reflectivity. SAR systems are indispensable in many remote sensing applications. Phase errors due to uncompensated platform motion degrade ...
    • Sparse ground-penetrating radar imaging method for off-the-grid target problem 

      Gurbuz, A. C.; Teke, O.; Arıkan, Orhan (SPIE, 2013)
      Spatial sparsity of the target space in subsurface or through-the-wall imaging applications has been successfully used within the compressive-sensing framework to decrease the data acquisition load in practical systems, ...
    • Super-resolution using multiple quantized images 

      Özçelikkale, Ayça; Akar, G. B.; Özaktas, Haldun M. (IEEE, 2010)
      In this paper, we study the effect of limited amplitude resolution (pixel depth) in super-resolution problem. The problem we address differs from the standard super-resolution problem in that amplitude resolution is ...
