Quantifying the effects of blood pressure changes on ballistocardiogram signals
(IEEE, 2017)Quantifying the effects of blood pressure (BP) changes on the ballistocardiogram (BCG) signal shape and features can potentially improve the understanding of this mechanical modality of cardiovascular sensing. BCG, a measure ... -
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 ...
