    • An Automated rule based visual printed circuit board inspection system which uses mathematical morphological image processing algorithms 

      Oğuz, Seyfullah Halit (Bilkent University, 1990)
      In this thesis, the design and implementation of an automated rule based visual printed circuit board (PCB) inspection system are presented. The developed system makes use of mathematical morphology based image processing ...
    • Automatic detection of geospatial objects using multiple hierarchical segmentations 

      Akçay, H. G.; Aksoy, S. (Institute of Electrical and Electronics Engineers, 2008-07)
      The object-based analysis of remotely sensed imagery provides valuable spatial and structural information that is complementary to pixel-based spectral information in classification. In this paper, we present novel methods ...
    • Cell nuclei segmentation in pap smear test images 

      Kale, A.; Aksoy, S.; Önder, S. (2009)
      Cervical cancer is a preventable disease and the dysplasia it causes can be scanned by using a pap smear test. It can be beneficial to develop a computer-assisted diagnosis system to make the pap smear test robust and ...
    • 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 ...
    • Morphological modeling of position-based spatial relationships 

      Cinbiş, R.G.; Aksoy, S. (2007)
      Spatial information plays a very important role in image understanding. Fuzzy mathematical morphology provides an effective basis for extracting binary and ternary spatial relationships by creating a fuzzy landscape where ...
    • Morphological subband decomposition structure using GF(N) arithmetic 

      Gurcan Metin Nafi, Gerek Omer, N.; Cetin, A.Enis; Gerek, O. N.; Cetin, A. E. (IEEE, Los Alamitos, CA, United States, 1996)
      Linear filter banks with critical subsampling and perfect reconstruction (PR) property have received much interest and found numerous applications in signal and image processing. Recently, nonlinear filter bank structures ...
    • Relative position-based spatial relationships using mathematical morphology 

      Gökberk Cinbiş, R.; Aksoy, S. (2007)
      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 ...
    • A supervised learning model for live cell segmentation 

      Koyuncu, C.F.; Durmaz I.; Cetin-Atalay, R.; Gunduz-Demir, C. (IEEE Computer Society, 2014)
      Automated cell imaging systems have been proposed for faster and more reliable analysis of biological events at the cellular level. The first step of these systems is usually cell segmentation whose success affects the ...
    • Surface profile determination from multiple sonar data using morphological processing 

      Başkent, D.; Barshan, B. (Sage Publications Ltd., 1999-08)
      This paper presents a novel method for surface profile determination using multiple sensors. Our approach is based on morphological processing techniques to fuse the range data from multiple sensor returns in a manner that ...
