  • Active sensor imaging by wavelet and Gabor theories 
    Demirkol, Aşkın (TAYLOR & FRANCIS LTD, 2008)
    In the present paper, two new algorithms are studied by taking advantage of time frequency analysis techniques. Wavelet and Gabor theories are applied to active imaging by sensors such as radars. This is achieved by ...
  • Adaptive reversible video watermarking based on motion-compensated prediction error expansion with pixel selection 
    Vural, Cabir; Baraklı, Burhan (SPRINGER LONDON LTD, 2016)
    In this study, a motion-compensated prediction error expansion-based adaptive reversible video watermarking algorithm is proposed. Blocks of motion-compensated frames are classified as smooth and non-smooth according to ...
  • Estimation of target density functions via range-angle beamforming 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (TAYLOR & FRANCIS LTD, 2009)
    This paper considers estimation of target density functions in 'range-angle' coordinates using two beamforming techniques. The distribution of the target densities in range-angle coordinates is estimated utilizing several ...
  • LECTURE NOTES IN COMPUTER SCIENCE 
    Demirkol, Aşkın; Demir, Zafer; Emre, Erol (SPRINGER-VERLAG BERLIN, 2005)
    In this paper, a new Target Density Function(TDF) is theorized to image the radar targets by a new estimation algorithm. TDF is represented in a specified manner. This method is developed by inspiring of ambiguity functions. ...
  • Reversible video watermarking using motion-compensated frame interpolation error expansion 
    Vural, Cabir; Baraklı, Burhan (SPRINGER LONDON LTD, 2015)
    In this study, a reversible video watermarking method based on motion-compensated frame interpolation error expansion is developed. Interframe correlation is exploited more efficiently as a result of using motion-compensated ...
