      Günay, O.; Töreyin, B. U.; Köse K.; Çetin, A. E. (2012)
      In this paper, an entropy functional based online adaptive decision fusion framework is developed for image analysis and computer vision applications. In this framework, it is assumed that the compound algorithm consists ...
    • Entropy-functional-based online adaptive decision fusion framework with application to wildfire detection in video 

      Gunay, O.; Toreyin, B. U.; Kose, K.; Cetin, A. E. (IEEE, 2012-01-09)
      In this paper, an entropy-functional-based online adaptive decision fusion (EADF) framework is developed for image analysis and computer vision applications. In this framework, it is assumed that the compound algorithm ...
    • Equiripple FIR filter design by the FFT algorithm 

      Çetin, A. E.; Gerek, Ö. N.; Yardımcı, Y. (Institute of Electrical and Electronics Engineers, 1997-03)
      The fast Fourier transform (FFT) algorithm has been used in a variety of applications in signal and image processing. In this article, a simple procedure for designing finite-extent impulse response (FIR) discrete-time ...
    • Filtered Variation method for denoising and sparse signal processing 

      Kose, K.; Cevher V.; Cetin, A.E. (2012)
      We propose a new framework, called Filtered Variation (FV), for denoising and sparse signal processing applications. These problems are inherently ill-posed. Hence, we provide regularization to overcome this challenge by ...
    • Projections onto convex sets (POCS) based optimization by lifting 

      Cetin, A.E.; Bozkurt, A.; Gunay O.; Habiboglu, Y.H.; Kose, K.; Onaran I.; Tofighi, M.; Sevimli, R.A. (2013)
      A new optimization technique based on the projections onto convex space (POCS) framework for solving convex and some non-convex optimization problems are presented. The dimension of the minimization problem is lifted by ...
    • Pulse shape design using iterative projections 

      Emre Guven H.; Enis Cetin, A. (2005)
      In this paper, the pulse shape design for various communication systems including PAM, FSK, and PSK is considered. The pulse is designed by imposing constraints on the time and frequency domains constraints on the ...
