  • A practical parallel implementation for TDLMS image filter on multi-core processor 
    Akgün, Devrim (SPRINGER HEIDELBERG, 2017)
    In this study, parallel implementation of adaptive image filtering algorithm based on two-dimensional least mean square method (TDLMS) where the weights are continuously adjusted during filtering was realized by proposed ...
  • Accelerated method for the optimization of quadratic image filter 
    Akgün, Devrim (IS&T & SPIE, 2019)
    Quadratic image filter involves the second-order multiplications of an input image mask in addition to linear terms, and determining the weights of the quadratic filter using optimization methods requires intense computational ...
  • 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 ...
  • iFER: facial expression recognition using automatically selected geometric eye and eyebrow features 
    Öztel, İsmail; Yolcu Öztel, Gözde; Öz, Cemil; Kazan, Serap; Filiz Bunyak (IS&T & SPIE, 2018)
    Facial expressions have an important role in interpersonal communications and estimation of emotional states or intentions. Automatic recognition of facial expressions has led to many practical applications and became one ...
  • IFMBE Proceedings 
    Bindal, Cuma (HEIDELBERGER PLATZ 3, D-14197 BERLIN, GERMANY, 2007)
    Biomaterials being natural or man-made are crucially important for comprising whole or part of living structures. In order to prolong the service life of biomaterials is of vital importance. In this research, the tribological ...
  • 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 ...
