Savitzky-Golay Filters and Application to Image and Signal Denoising
(2018-07-18)
We explore the applicability of local polynomial approximation of signals for noise suppression. In the context of data regression, Savitzky and Golay showed that least-squares approximation of data with a polynomial of ...
Optimum Savitzky-Golay Filtering for Signal Estimation
(2018-03-21)
Motivated by the classic works of Charles M. Stein, we focus on developing risk-estimation frameworks for denoising problems in both one-and two-dimensions. We assume a standard additive noise model, and formulate the ...
