Spectral smoothing: splines and Savitzky-Golay filters

hyperSpec offers several ways for spectral smoothing:

• loess via function spc.loess
• binning of wavelenghts via function spc.bin
• smoothing splines via function spc.smooth.spline
• Several further filter, e.g. Savitzky-Golay smoothing, are available in package savgol. This funciton can be applied directly to the hyperSpec object:
