    • Piecewise smooth signal denoising via principal curve projections 

      Özertem, Umut; Erdoğmuş, D.; Arıkan, Orhan (IEEE, 2008-10)
      One common problem in signal denoising is that if the signal has a blocky, in other words a piecewise-smooth structure, the denoised signal may suffer from oversmoothed discontinuities or exhibit artifacts very similar to ...

    • Signal denoising by piecewise continuous polynomial fitting 

      Yıldız, Aykut; Arıkan, Orhan (IEEE, 2010)
      Piecewise smooth signal denoising is cast as a non-linear optimization problem in terms of transition boundaries and a parametric smooth signal family. Optimal transition boundaries for a given number of transitions are ...
