    • Polynomial fitting and total variation based techniques on 1-D and 2-D signal denoising 

      Yıldız, Aykut (Bilkent University, 2010)
      New techniques are developed for signal denoising and texture recovery. Geometrical theory of total variation (TV) is explored, and an algorithm that uses quadratic programming is introduced for total variation reduction. ...
    • Real-time cancellation using ICA-PSO-PE 

      Bor, Remziye İrem (Bilkent University, 2012)
      A real-time implementable noise cancellation algorithm is developed. Speech and noise sources are not known but only their mixtures are observed. A mobile radio system is modelled with instantaneous mixture model as the ...
