  • 2-D generating function of the zernike polynomials and their application for image classification 
    Honarvar Shakibaei Asli, Barmak; Flusser, Jan; Zhao, Yifan (IEEE, 2019-12-19)
    This work proposes a new approach to find the generating function (GF) of the Zernike polynomials in two dimensional form. Combining the methods of GFs and discrete-time systems, we can develop two dimensional digital ...
  • Filter-generating system of Zernike polynomials 
    Honarvar Shakibaei Asli, Barmak; Flusser, Jan; Zhao, Yifan; Erkoyuncu, John Ahmet (Elsevier, 2019-07-24)
    This work proposes a new approach to find the generating function (GF) of the Zernike polynomials in two dimensional form. Combining the methods of GFs and discrete-time systems, we can develop two dimensional digital ...
  • Four-term recurrence for fast Krawtchouk moments using Clenshaw algorithm 
    Barmak, Honarvar Shakibaei Asli; Rezaei, Maryam Horri (MDPI, 2023-04-12)
    Krawtchouk polynomials (KPs) are discrete orthogonal polynomials associated with the Gauss hypergeometric functions. These polynomials and their generated moments in 1D or 2D formats play an important role in information ...
  • Ultrasound image filtering and reconstruction using DCT/IDCT filter structure 
    Honarvar Shakibaei Asli, Barmak; Flusser, Jan; Zhao, Yifan; Erkoyuncu, John Ahmet; Krishnan, Kajoli Banerjee; Farrokhi, Yasin; Roy, Rajkumar (IEEE, 2020-07-27)
    In this paper, a new recursive structure based on the convolution model of discrete cosine transform (DCT) for designing of a finite impulse response (FIR) digital filter is proposed. In our derivation, we start with the ...
