We bring in the concept of Fourier ring correlation for another riff on the optimal settings of smoothing filters.
Locally weighted regression is an approach for smoothing a set of data points by performing a polynomial regression in the vicinity of each point. It does sounds like a …
On the concept of wavelet transform and decomposition, and its application for denoising of spectra.
Setting the parameters of a Savitzky-Golay filter seems more a craft than a science. Here's my method to find an optimal filter, complete with code.
Meet a fairly unknown member of the spectral smoothing family: the Fourier spectral smoothing method. Learn some theory and Python code implementation.
The secret behind perfect smoothing is a wise choice of parameters. In this tutorial you will learn about the Savitzky–Golay method and the way to optimise its performance
Worked example of two scatter correction techniques for NIR spectroscopy in Python: Multiplicative Scatter Correction and Standard Normal Variate.
