Piecewise smooth signal denoising via principal curve projections
(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
(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 ...
