    • A aurvey of signal processing problems and tools in holographic three-dimensional television 

      Onural, L.; Gotchev, A.; Özaktaş, Haldun M.; Stoykova, E. (Institute of Electrical and Electronics Engineers, 2007)
      Diffraction and holography are fertile areas for application of signal theory and processing. Recent work on 3DTV displays has posed particularly challenging signal processing problems. Various procedures to compute ...
    • Bessel functions-based reconstruction of non-uniformly sampled diffraction fields 

      Uzunov, V.; Esmer, G. Bora; Gotchev, A.; Onural, Levent; Özaktaş, Haldun M. (IEEE, 2007)
      A discrete computational model for the diffraction process is essential in forward problems related to holographic TV. The model must be as general as possible, since the shape of the displayed objects does not bear any ...
    • Diffraction field computation from arbitrarily distributed data points in space 

      Esmer, G. B.; Uzunov, V.; Onural, L.; Özaktaş, Haldun M.; Gotchev, A. (Elsevier BV, 2007-02)
      Computation of the diffraction field from a given set of arbitrarily distributed data points in space is an important signal processing problem arising in digital holographic 3D displays. The field arising from such ...
    • An overview of the holographic display related tasks within the European 3DTV project 

      Onural, Levent; Özaktaş, Haldun M.; Stoykova, E.; Gotchev, A.; Watson J. (SPIE, 2006)
      A European consortium has been working since September 2004 on all video-based technical aspects of three-dimensional television. The group has structured its technical activities under five technical committees focusing ...
    • Performance assessment of a diffraction field computation method based on source model 

      Esmer, G. Bora; Onural, Levent; Özaktaş, Haldun M.; Uzunov, V.; Gotchev, A. (IEEE, 2008-05)
      Efficient computation of scalar optical diffraction field due to an object is an essential issue in holographic 3D television systems. The first step in the computation process is to construct an object. As a solution for ...
    • Reconstruction of scalar diffraction field from distributed data points over 3D space 

      Esmer, G. Bora; Uzunov, V.; Onural, Levent; Gotchev, A.; Özaktaş, Haldun M. (IEEE, 2007)
      Diffraction field computation is an important task in the signal conversion stage of the holographic 3DTV. We consider an abstract setting, where the diffraction field of the desired 3D scene to be displayed is given by ...
    • Signal processing problems and algorithms in display side of 3DTV 

      Ulusoy, E.; Esmer, Gökhan Bora; Özaktaş, Haldun M.; Onural, Levent; Gotchev, A.; Uzunov, V. (IEEE, 2006-10)
      Two important signal processing problems in the display side of a holographic 3DTV are the computation of the diffraction field of a 3D object from its abstract representation, and determination of the best display ...
    • Three-dimensional media for mobile devices 

      Gotchev, A.; Akar, G. B.; Capin, T.; Strohmeier, D.; Boev, A. (Institute of Electrical and Electronics Engineers, 2011-04)
      This paper aims at providing an overview of the core technologies enabling the delivery of 3-D Media to next-generation mobile devices. To succeed in the design of the corresponding system, a profound knowledge about the ...
    • Three-dimensional monochromatic light field synthesis with a deflectable mirror array device 

      Ulusoy, Erdem; Uzunov, V.; Onural, Levent; Özaktaş, Haldun M.; Gotchev, A. (SPIE, 2006)
      We investigated the problem of complex scalar monochromatic light field synthesis with a deflectable mirror array device (DMAD). First, an analysis of the diffraction field produced by the device upon certain configurations ...
